If you want to enter the Kingdom of Heaven and have eternal life you will have to follow and obey Jesus Christ. Jesus came, not to do His own will, but the will of the Father.
Jesus said:"49I have not spoken on My own, but the Father who sent Me has commanded Me what to say and how to say it. 50And I know that His command leads to eternal life. So I speak exactly what the Father has told Me to say.”John 12:49,50.
God is not interested in the doctrines and opinions of men and churches, neither in their interpretations of the Bible. Jesus came and delivered the words of eternal life. Those who reject and disobey the words of Jesus will NOT enter heaven. They will not have eternal life. Jesus said:47As for anyone who hears My words and does not keep them, I do not judge him. For I have not come to judge the world, but to save the world. 48There is a judge for the one who rejects Me and does not receive My words: The word that I have spoken will judge him on the last day."John 8,47-48.
The words of Jesus, the words of eternal life, were recorded in the gospels, Matthew, Mark, Luke and John. If you do not understand what Jesus meant, pray, ask Him, and He will give you understanding. If you obey His words, He will reveal Himself to you. He will, guide and teach you. If you follow and obey Him, He will lead you to eternal life.
Obey Jesus, repent, stop sinning, be baptized in water. Deny yourself, stop going after your own desires and lusts, your own opinion. Go after Jesus. He will come and dwell with you, in you, with you. If you stay with Him and keep on obeying Him, He will lead you to eternal life.
Jesus is Lord, obey and follow Him or else you will not enter the kingdom of heaven and have eternal life.
May Jesus bless you.
