Why believers do not stop sinning

There are many reasons why BELIEVERS keep on sinning. One of the main reasons is that people BELIEVE LIES that other people tell them and they do not take Jesus Christ seriously. If they really believe in Jesus, they will immediately stop sinning and obey His Words. The Words of Jesus as also recorded in the Gospels, Matthew, Mark, Luke and John are the Words of eternal life and we will be judged by those Words. Those who OBEY the Words of Jesus will have LIFE but those who DISOBEY Him will perish. If you truly follow Jesus Christ, you will live according to HIS WORDS as they are also recorded in the Gospels, because if you do not obey Jesus you will have no relationship with Him whatsoever. 
Jesus does not have fellowship with sinners. Sin separates you from Jesus. The moment you disobey Him, that sin separates you from Him. If you seriously want to follow Jesus then He will immediately put you right. He will immediately warn you, chastise you but He will not allow you to sin. If you follow Jesus, you WILL NOT SIN. It is because people are NOT following Jesus Christ, they have NO relationship with Him. They do not know His voice, they do not listen to Him. They do not CARE to hear His voice because they THINK that they have salvation. They have been deceived. His sheep LISTEN to His voice and they follow Him. They do not go after sin, they go after Jesus. They do not go after their own affairs. They go after the Kingdom of God. Their focus is on Jesus, they live for Him. 
Jesus said: Whoever WISHES to come after Me must deny himself, pick up his cross every day and come here and follow Me. YOU CANNOT SIN AND FOLLOW Jesus Christ. If you are in any sin, lies, fornication, pornography, then you are not following Jesus, you are not IN Christ, you are IN SIN and in danger of hellfire. You CANNOT SIN and follow Jesus Christ. If you follow Jesus, you obey Him. You do everything exactly as He commanded. You REPENT, you turn away from sin, you’re baptized in water for the washing off of your sin and then you live in UTTER HOLINESS and OBEDIENCE TO HIM every day of your life until the very last day of your life. You seek to please Him. You are in relationship with Him. All that matters to you is to be pleasing to Jesus. If we do not obey Him, we will perish. If you follow Jesus Christ you will stop sinning. May Jesus bless you.
