1 John 2:1-2 NKJV
My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.  And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
Romans 5:18-21 NKJV
Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one Man’s righteous act the free gift came to all men, resulting in justification of life.  For as by one man’s disobedience many were made sinners, so also by one Man’s obedience many will be made righteous.  Moreover the law entered that the offense might abound. But where sin abounded, grace abounded much more,  so that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord.
Galatians 3:22-29 NKJV
But the Scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe.  But before faith came, we were kept under guard by the law, kept for the faith which would afterward be revealed.  Therefore the law was our tutor (schoolmaster) to bring us to Christ, that we might be justified by faith.  But after faith has come, we are no longer under a tutor (schoolmaster).  For you are all sons of God through faith in Christ Jesus.  For as many of you as were baptized into Christ have put on Christ.  There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.  And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.
Salvation and Eternal Life are offered as a free gift of God’s grace to anyone who will accept it, and that anyone who will may come! It is only the voluntary act of our own wills that is required. However, there are and will be many of whom Jesus must say:
“Ye will not come to me, that ye might have life” (John 5:40).
Matthew 24:14 KJV
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
