Jesus Christ said that you must be born again to enter the kingdom of heaven. Not all believers are born again and not all those who have been born again will enter into the kingdom of heaven. If you hear the gospel of Jesus Christ and you believe and you go on your knees before Jesus, you humble yourself before Him and you pray from your heart, you accept Him into your life as your Lord and Master, then you will be born again. You will have an experience with Jesus Christ where you will know that He is real and that He has accepted you, and that He has forgiven your sins, you are born again, you have the made a child of God. You will experience Jesus Christ as Lord, but it does not stop there.
Many people are born again and they receive Jesus Christ but then they turn away from Him, they do not follow Him. Once you have been born again you will forever be a child of God, but it does not mean that you are an obedient child of God. Only the obedient children of God are pleasing to Him. If you have been born again and become a child of God, then God treats you as a child. Then His Holy Spirit will immediately convict you of all sin, but you have to obey Him. You have to turn away from that sin, and you have to seek to please Jesus. You must listen to the voice of the Holy Spirit in you. If you refuse to obey, if you ignore Him, He will discipline you. Many born-again children of God are back-slidden and they are under the chastisement of the Holy Spirit.It is because God cares for you, He treats you as His child, but you have to respond and you have to obey Him. If you disobey Him you will perish. The discipline and the correction of God is for His own children, not for the world. He disciplines His own children. That is why those who were born again and who backslide are always under conviction. They are always under conviction whenever they do wrong. They know that God is not pleased with them. Many do not have the confidence to go back to God, but it is the only way to have life. You have to repent and go back to Jesus.
Many believers are professing sinners .They say we are all sinners. They have never been born again. If you have met Jesus Christ and you are born again child of God, you will immediately be convicted when you even think wrong, when you do wrong, because the Spirit of God will convict you, the Holy Spirit that He gave to be with you.
The Holy Spirit will not leave you but if you keep on disobeying Him, you will perish in the end. The difference between a common believer and a person that has been born again, is that a born-again child of God lives under conviction. Many of them have seared their consciences. They have ignored the Holy Spirit so much that their hearts have been hardened. There is hope for every soul that wishes to repent. Do not let anything stop you from going back to Jesus. the door is open. Jesus never turns His back on His own. It is not the will of God that anyone perish, but that all repent and have life.
Jesus loves you and cares for you and He never changes. He never leaves you, He never forsakes you but if you keep on disobeying Him, disregarding Him then you will perish in the end. If you were never born again, go on your knees and ask Jesus to make you new inside to make your child of God and then obey Him; be baptized in water, seek Him more and more, seek His indwelling Holy Spirit, listen to Him, obey Him. Follow Him and He will teach and guide you. If you are born again and you are backslidden, run back to Jesus. Repent from your heart and seek Him with all your heart. The way back will not be easy but it is the only way. Remember, the chastisement of God is for His children. He cares for us, He disciplines us. He chastises us and we learn through what what we suffer. God does not give up on us but He does not treat us with kid gloves. God often treats as harshly, He disciplines us harshly so that we can learn not to stray, that we can learn to obey Him so that we can be fruitful for His kingdom. He prunes every branch that bears fruit, and that pruning is not pleasant, but it is needed for us to bear more fruit, because if we do not bear fruit, we will get cut off and burned, and we can only bear fruit if we remain in Christ, if we are led by the Holy Spirit.
We cannot follow Jesus Christ by trusting in our own mind and our own interpretation of the Bible. We need to be led by the Holy Spirit. We need to be close to Jesus, in close relationship with Him as children of God, and He will guide us. He will teach us and we must obey Him, then we will bear fruit for His kingdom, we will be pleasing to Him. You have to be born again to enter kingdom of God, and you have to obey Jesus Christ, and follow Him until the very end to be saved. Nobody is finally saved until the very end. We must endure with Jesus until the end.
May Jesus bless you.
