For Jesus, faith is not opposed to not believing in God, it doesn’t mean you go to church, or that you’re into religion or that you say “Lord, Lord!” (see Matthew 7:21). Faith for Jesus is the opposite of anxiety. If you are anxious, if you are trying to control everything, if you are worried about many things, you don’t have faith, according to Jesus. You do not trust that God is good and on your side. You’re trying to do it all yourself, lift yourself up by your own bootstraps. The giveaway is control. That’s a good litmus test of the quality of your faith. People of faith don’t have to control everything, nor do they have to change people. You have the wisdom to know the difference, as the Twelve-Step people say. You cannot “fix” the soul. “Set your hearts on his kingdom first, and on God’s saving justice, and all these other things will be given you as well. So do not worry about tomorrow: tomorrow will take care of itself ’” (Matthew 6:33-34a).
