If you cannot stop sinning you cannot enter the kingdom of heaven, and that is why Jesus came, to take away the sins of the world. He makes us FREE FROM SIN, if we accept Him and we are born again.
Those who are born again of the Spirit of God SIN NO MORE because they have victory over sin. Whoever the Son of God has set free, will be free and free indeed.
We have to resist the devil and overcome sin, because sin separates us from God. The wages of sin is death. without holiness no man shall see God. We have to live in utter holiness and obedience to Jesus Christ. We have to overcome the battle against sin and live holy and righteously in obedience to Jesus Christ.
Only those who overcome will enter the kingdom of heaven. Are we winning in the struggle against sin?
May Jesus bless you.
