As you witness, divorce yourself from the thought that you are merely seeking “decisions for Christ.” What we should be seeking is repentance within the heart that produces a Godly sorrow, not worldly sorrow. This is the purpose of the Law, to bring the knowledge of sin. How can a man repent if he doesn’t know what sin is?
Galatians 3:24-25 KJV
Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.  But after that faith is come, we are no longer under a schoolmaster.
Psalm 19:7 KJV
The law of the Lord is perfect, converting the soul: the testimony of the Lord is sure, making wise the simple.
The 10 Commandments reveals what sin is and brings a person to the foot of The Cross of Christ, where a decision must be made. Repent and follow Christ for Salvation or continue in sin and continue on the path of destruction you are already on. Without Jesus you are condemned already.
John 3:14-18 KJV
And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:  That whosoever believeth in him should not perish, but have eternal life.  For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.  For God sent not his Son into the world to condemn the world; but that the world through him might be saved.  He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
If there is no repentance, there is no salvation. Jesus said, “Unless you repent, you shall all likewise perish” (Luke 13:3). God is not willing that any should perish, but that all should come to repentance (2 Peter 3:9).
Many don’t understand that the salvation of a soul is not a resolution to change a way of life, but “repentance toward God, and faith toward our Lord Jesus Christ.” The modern concept of success in evangelism is to relate how many people were “saved” (that is, how many prayed the “sinner’s prayer”). This produces a “no decisions, no success” mentality. This shouldn’t be, because Christians who seek decisions in evangelism become discouraged after a time of witnessing if “no one came to the Lord.” The Bible tells us that as we sow the good seed of the gospel, one sows and another reaps. If you faithfully sow the seed, someone will reap. If you reap, it is because someone has sown in the past, but it is God who causes the seed to grow and gives the increase. If the hand of God is not on the person you are leading in a prayer of committal, if there is not God-given repentance, and Godly sorrow for sin, then you will end up with a stillbirth on your hands, and that is nothing to rejoice about. We should measure our success by how faithfully we sowed the seed of The Gospel. In that way, we will avoid becoming discouraged.
The road to repentance is godly sorrow.
(2 Corinthians 7:10 NKJV)
For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death.
Godly sorrow is developed when we focus on the true nature of sin as an offense against God rather than something that makes us feel guilty. Sin is an affront to God’s holiness, it grieves his Holy Spirit, and it wounds afresh the Lord Jesus Christ. It also gratifies Satan, the archenemy of God. Dwelling on the true nature of sin leads us to godly sorrow, which in turn leads us to repentance.
Having come to repentance, we must by faith lay hold of the cleansing blood of Jesus Christ, which alone can cleanse our consciences. In fact, it is faith in Jesus Christ, and the assurance of his cleansing Blood that leads us to repentance.
Jesus Christ says,
Luke 13:3-5 NKJV
I tell you, no; but unless you repent you will all likewise perish.  Or those eighteen on whom the tower in Siloam fell and killed them, do you think that they were worse sinners than all other men who dwelt in Jerusalem?  I tell you, no; but unless you repent you will all likewise perish.”
Billy Graham says,
“If you have not repented of your sins, you will not see the inside of the kingdom of God.”
But more importantly…It’s what Jesus Christ says…In Jesus Name…Amen.
Unless you are Born Again…you cannot see the Kingdom Of God.
And whosoever was not found written in the book of life was cast into the lake of fire.
