unless you are converted...., you will by no means enter the kingdom of heaven

Matthew 18:3
and said, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven.

When we are first converted, most of us come to the Throne of God as little children, in submission of our will, even in if that is just temporary. We must keep being converted in the sense of working out our salvation. Everyday may bring new and different battles. There will always be temptations trying to draw us into acting opposite to God's will. So we continue to submit our self will and be led by the Spirit of God.
