The kingdom of God grows in our hearts like yeast that starts out small, but works its way through the whole batch. In the same way the behaviors of the kingdom become habits that crowd out old (non-helpful), non-healthful behaviors. Judgementalism is crowded out by humility; rule keeping is crowded out by mercy; Useless debating is crowded out by hungering and thirsting for righteousness; and fear is crowded out by listening to God's opinion.
So roll up your sleeves, put your mind in gear, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy. [1 Peter 1:13-16]
