The definition of grace has been twisted into pernicious lies by the false prophets. They say when you repeat the "sinners prayer" or say that Jesus is Lord and/or get baptised, you instantly receive the grace of God to forgive all your past, present, and future sins; excusing you to live the remainder of your life in sin, with their guarantee of you going to heaven when you die.

Consider how completely different the Apostle Paul in Titus defines grace: (what we must be saved by)

For the grace of God that brings salvation has appeared to all men,
teaching us that, denying ungodliness and worldly lusts,
we should live soberly, righteously, and godly, in this present world,
looking for that blessed hope, and the glorious appearing of the great God and our Savior Jesus Christ;
who gave himself for us, that he might redeem us from all iniquity,
and purify unto himself a peculiar people, zealous of good works. Titus 2:11-14

Grace teaches us to deny ungodliness and to live righteously and godly in this present world. So to become purified and zealous for good works. Denying ungodliness and worldly lusts is repentance. Grace leads us to repentance. Grace leads us to the inward cross of self-denial, so that we can crucify our sinful nature, to become free from all iniquity and be pure. This is Paul's definition of grace. Can you see how different Paul's definition of grace is from the definition of instant, no-effort grace you have been sold by the false prophets?

One who still sins might mistakenly argue they are redeemed from all iniquity, but not that grace has purified them!

Grace has been twisted into lies from a teaching of repentance, leading to purity, to be a license for immorality and continuing in our sinful natures with no repentance required. This perversion began 2000 years ago in the early church; Jude wrote in 1:4:

For certain men, whose condemnation was written about long ago, have secretly slipped in among you. They are godless men, who change the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.  

These men were false Christians, who had slipped unnnoticed among the true Christians, preaching freedom to sin through grace by faith in Jesus, but denying Christ to rule their words and actions as their sovereign and Lord, as he did with the real Christians of that time. The false gospel of grace was being sold as salvation 2000 years ago; unfortunately false instant salvation, has become universal, all sects being deficit sects. See the Great Apostasy for more information.

See True Grace vs. False Grace for a complete discussion of how the definition of grace has been twisted into malicious lies.

Your sinful nature must be crucified on the inward cross of self-denial, before you receive the powerful grace of God to circumcise your heart, renew your mind, and to be born again as an entirely new creature. Then you will walk in perfect obedience to God's commands. You cannot be obedient or be pleasing to God continuing walk in your carnal nature, (sinful nature, or flesh.)
