This generation of Christians was never taught to repent. False preachers told them that they only need to believe in Jesus to have eternal life. They were taught to admit that they are sinners, but were not told to turn away from sin, to stop sinning. They believe a false gospel that is not the gospel of Jesus Christ.
The wages of sin is death. As long as you keep on sinning you are damned and on your way to hell. Jesus came to take away the sins of the world. He pardons those who accept Him as Lord and obey Him, His words and commandments as also recorded in Matthew, Mark, Luke and John, which is the true gospel.
Jesus commanded His disciples to: “Go into all the world and preach the gospel to all creation. 16“He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned.” Mark 16:15,16.
The gospel of Jesus Christ is about repentance, holiness and obedience to Jesus. Unless a person repents, stops sinning and lives holy, he cannot follow Jesus neither enter the kingdom of God. It all starts with repentance.
Most professing Christians never repented. They believe they are saved based on the false grace gospel and other deceptive teachings of men. They ignore or deliberately forget the words of Jesus while they choose to believe lies and false doctrines. They disbelieve the words of the apostle John in 1 John 3:4-10 “Everyone who practices sin also practices lawlessness; and sin is lawlessness. 5You know that He appeared in order to take away sins; and in Him there is no sin. 6No one who abides in Him sins; no one who sins has seen Him or knows Him. 7Little children, make sure no one deceives you; the one who practices righteousness is righteous, just as He is righteous;8the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil. 9No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. 10By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother.”
No sinners will enter heaven. Without holiness no one will see the Lord. 99.9% of the modern day Christians are on their way to hell, because they are sinners. They never repented, and by their deeds they prove to be children of the devil.
There is only one way to be saved: Repent and be baptized, stop sinning, be holy, live in obedience to the teachings and commandments of Jesus. If you obey Him, He will give His Holy Spirit in you to teach and guide you into all truth. If you follow and obey Him, until the end, you will have eternal life. If along the way, you stray and fall into sin, immediately repent and go back to Jesus, stay with Him until the end, or it would have been all in vain.
May Jesus bless you.
