Prayer is mysterious. Jesus demystifies it by encouraging us simply to start praying. If we need something? Ask God for it. If we have a cry for justice, then shout it out. The newest part of this teaching by Jesus seems to be the shock that someone wouldn’t pray for their needs or the needs of others. What’s the difference? Jesus knows God as Father, a loving parent. Of course there’s room to bring all of our needs before that kind of God.
