That's why it only makes sense that you believe and "repent" (a bad translation of
metanoia) - let yourself be transformed/renewed to enter new life with Lord (the kingdom). Not by just believing it will automatically happen after you die. Yes, God saves but how can you be friends with someone without building
together a close relationship? Without preparing the way for your Lord?
Who may ascend the mountain of the LORD? Who may stand in his holy place? The one who has clean hands and a pure heart. (Psalm 24:3-4)
Nothing impure will ever enter it... (Relevation 21:27)
And a lawyer stood up and put Him to the test, saying, “Teacher, what shall I do to inherit eternal life?” And He said to him, “What is written in the Law? How does it read to you?” And he answered, “YOU SHALL LOVE THE Lord /... / And He said to him, “You have answered correctly; DO THIS AND YOU WILL LIVE.” (Luke 10:25-28)
Etc.
What will we take with us when we die? What will endure this "judgment"? Faith and hope are important guides but they remain only for this life (later we will
know directly). Love is eternal. Love is the greatest. Without love I'm nothing.
