In Matthew 5:48 in NASB Jesus calls us to be perfect as our heavenly Father is perfect. I love how The Message says it: "In a word, what I'm saying is, Grow up. You're kingdom subject. Now live like it. Live out your God-created identity. Live generously and graciously toward others, the way God lives toward you."
How God often works (according to Eugene H. Peterson) is through quietness and prayer.
So I guess, if we are going to be like our Father, that is how we should work too.
