When is Jesus Coming back ?
Are there signs ?
What saith The Scriptures?
Matthew 24:1-51 NKJV
Then Jesus went out and departed from the temple, and His disciples came up to show Him the buildings of the temple.  And Jesus said to them, “Do you not see all these things? Assuredly, I say to you, not one stone shall be left here upon another, that shall not be thrown down.”  Now as He sat on the Mount of Olives, the disciples came to Him privately, saying, “Tell us, when will these things be? And what will be the sign of Your coming, and of the end of the age?”  And Jesus answered and said to them: “Take heed that no one deceives you.  For many will come in My name, saying, ‘I am the Christ,’ and will deceive many.  And you will hear of wars and rumors of wars. See that you are not troubled; for all these things must come to pass, but the end is not yet.  For nation will rise against nation, and kingdom against kingdom. And there will be famines, pestilences, and earthquakes in various places.  All these are the beginning of sorrows.  “Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name’s sake.  And then many will be offended, will betray one another, and will hate one another.  Then many false prophets will rise up and deceive many.  And because lawlessness will abound, the love of many will grow cold.  But he who endures to the end shall be saved.  And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.  “Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place” (whoever reads, let him understand),  “then let those who are in Judea flee to the mountains.  Let him who is on the housetop not go down to take anything out of his house.  And let him who is in the field not go back to get his clothes.  But woe to those who are pregnant and to those who are nursing babies in those days!  And pray that your flight may not be in winter or on the Sabbath.  For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be.  And unless those days were shortened, no flesh would be saved; but for the elect’s sake those days will be shortened.  “Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There!’ do not believe it.  For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect.  See, I have told you beforehand.  “Therefore if they say to you, ‘Look, He is in the desert!’ do not go out; or ‘Look, He is in the inner rooms!’ do not believe it.  For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be.  For wherever the carcass is, there the eagles will be gathered together.  “Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken.  Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.  And He will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other.  “Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near.  So you also, when you see all these things, know that it is near-at the doors!  Assuredly, I say to you, this generation will by no means pass away till all these things take place.  Heaven and earth will pass away, but My words will by no means pass away.  “But of that day and hour no one knows, not even the angels of heaven, but My Father only.  But as the days of Noah were, so also will the coming of the Son of Man be.  For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark,  and did not know until the flood came and took them all away, so also will the coming of the Son of Man be.  Then two men will be in the field: one will be taken and the other left.  Two women will be grinding at the mill: one will be taken and the other left.  Watch therefore, for you do not know what hour your Lord is coming.  But know this, that if the master of the house had known what hour the thief would come, he would have watched and not allowed his house to be broken into.  Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.  “Who then is a faithful and wise servant, whom his master made ruler over his household, to give them food in due season?  Blessed is that servant whom his master, when he comes, will find so doing.  Assuredly, I say to you that he will make him ruler over all his goods.  But if that evil servant says in his heart, ‘My master is delaying his coming,’  and begins to beat his fellow servants, and to eat and drink with the drunkards,  the master of that servant will come on a day when he is not looking for him and at an hour that he is not aware of,  and will cut him in two and appoint him his portion with the hypocrites. There shall be weeping and gnashing of teeth.
Matthew 25:13 NKJV
“Watch therefore, for you know neither the day nor the hour in which the Son of Man is coming.
Mark 13:32-37 NKJV
“But of that day and hour no one knows, not even the angels in heaven, nor the Son, but only the Father.  Take heed, watch and pray; for you do not know when the time is.  It is like a man going to a far country, who left his house and gave authority to his servants, and to each his work, and commanded the doorkeeper to watch.  Watch therefore, for you do not know when the master of the house is coming-in the evening, at midnight, at the crowing of the rooster, or in the morning-  lest, coming suddenly, he find you sleeping.  And what I say to you, I say to all: Watch!”
No one knows when Jesus will return except God The Father.
2 Peter 3:1-18 NKJV
Beloved, I now write to you this second epistle (in both of which I stir up your pure minds by way of reminder),  that you may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us, the apostles of the Lord and Savior,  knowing this first: that scoffers will come in the last days, walking according to their own lusts,  and saying, “Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation.”  For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water,  by which the world that then existed perished, being flooded with water.  But the heavens and the earth which are now preserved by the same word, are reserved for fire until the day of judgment and perdition of ungodly men.  But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.  The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance.  But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.  Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness,  looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?  Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells.  Therefore, beloved, looking forward to these things, be diligent to be found by Him in peace, without spot and blameless;  and consider that the longsuffering of our Lord is salvation-as also our beloved brother Paul, according to the wisdom given to him, has written to you,  as also in all his epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures.  You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked;  but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen.
2 Timothy 3:1-17 NKJV
But know this, that in the last days perilous times will come:  For men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,  unloving, unforgiving, slanderers, without self-control, brutal, despisers of good,  traitors, headstrong, haughty, lovers of pleasure rather than lovers of God,  having a form of godliness but denying its power. And from such people turn away!  For of this sort are those who creep into households and make captives of gullible women loaded down with sins, led away by various lusts,  always learning and never able to come to the knowledge of the truth.  Now as Jannes and Jambres resisted Moses, so do these also resist the truth: men of corrupt minds, disapproved concerning the faith;  but they will progress no further, for their folly will be manifest to all, as theirs also was.  But you have carefully followed my doctrine, manner of life, purpose, faith, longsuffering, love, perseverance,  persecutions, afflictions, which happened to me at Antioch, at Iconium, at Lystra-what persecutions I endured. And out of them all the Lord delivered me.  Yes, and all who desire to live godly in Christ Jesus will suffer persecution.  But evil men and impostors will grow worse and worse, deceiving and being deceived.  But you must continue in the things which you have learned and been assured of, knowing from whom you have learned them,  and that from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus.  All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,  that the man of God may be complete, thoroughly equipped for every good work.
God Has Chosen Through His Wisdom, not mans.
1 Corinthians 1:21-31 NKJV
For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe.  For Jews request a sign, and Greeks seek after wisdom;  but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness,  but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.  Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.  For you see your calling, brethren, that not many wise according to the flesh, not many mighty, not many noble, are called.  But God has chosen the foolish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty;  and the base things of the world and the things which are despised God has chosen, and the things which are not, to bring to nothing the things that are,  that no flesh should glory in His presence.  But of Him you are in Christ Jesus, who became for us wisdom from God-and righteousness and sanctification and redemption-  that, as it is written, “He who glories, let him glory in the LORD.”
