There are few spiritual disciplines more difficult, and yet more absolutely necessary, than prayer. Jesus is clear: we should never stop praying! Our Father delights in us and wants to take care of us. This is not a blanket promise, though; as Alistair Begg notes, we’re not always good at knowing what to pray for, and pride and selfishness often get in our way. Thankfully, the Bible provides models for us—men and women who let submission to God guide their prayers.
