We cannot be perfect apart from others. The Bible links perfection with human relationships. Christ urges us to be as perfect as our Father in heaven and ties the process to how we treat each other. The Kingdom of God is about eternal, peaceful relationships. We cannot withdraw from people and still develop the necessary relationship skills, just as God never leaves us but continues to work with us. Life would be easier for Him if He ignored us, but He works on, helping us develop our relationships with Him. He is the One who works perfection in us.

Basic Doctrines: Going On to Perfection
Sanctification will be seen and heard "for out of the abundance of the heart his mouth speaks." If the heart has been impregnated by the Spirit of God, the mouth will begin to speak like God does! A person's works produce the fruits, and the heart then is known by what it produces.
This produces a peculiar effect within the converted person. While good fruit is showing, the converted person sees himself thoroughly encompassed by weakness. For instance, whenever Moses came down from the mount, after being with God, his face radiated the reflected glory of God. But he was not aware of it that his face was glowing!
There is a New Testament equivalent of this in Matthew 25. In the Parable of the Sheep and the Goats, Jesus separates the sheep on one side and the goats on the other. What do the sheep say to their lord and master? "When did we feed you? When did we clothe you?" They were not aware that they were producing the right fruit and reflecting God's glory in their lives.
