We can only fit into the kingdom of God if we OBEY Him, if we OBEY the words of Jesus, the words He spoke as also written in the gospels, Matthew, Mark, Luke and John.
Repent and be baptized in water, live in righteousness and holiness, and Jesus will REVEAL HIMSELF to you. He will give the Holy Spirit to live IN YOU and guide you but you have to OBEY. If you disobey the guidance of the Holy Spirit you reject Jesus and you DO NOT FIT into the kingdom of heaven, you are a castaway (reject), you are useless. All that matters to God is utter and total obedience.
Do you LISTEN, OBEY and FOLLOW the guidance of the Holy Spirit or do you not FIT INTO the kingdom of God.
May Jesus bless you.
