The transition from outside the kingdom into the kingdom happens all at once.
The transition of the character of the lives that have gone from completely outside to completely inside takes longer.

As Joel Littlefield writes Things That Matter Rarely Happen Fast.

Jesus said that the Kingdom of God is like a mustard seed. Compared to the tree that it produces, it’s among the smallest of seeds. Being a Christian in this Kingdom will mean that what is being produced in us by Jesus, though it be small and comparatively insignificant right now, will one day have influence that spreads like the branches of a large tree. Seeds are planted and may not sprout for days. Yet with time and patience, fruit comes.
Faith in the Son of God is not about fast changes. It’s about truth hidden in our hearts that is doing something now, and will one day spring forth as great trees producing more fruit than we can imagine.
