Remember how, at the start of your Christian walk, you were diligent to pray whenever you could, because prayer seemed like the most instinctive and comforting thing to do? But maybe over the years, praying has become harder. You feel like you don't know what to say, and if you do think of something to pray for, you also don't know what to expect, what the outcome will be. Besides, do we really have to say it out loud if God already knows what we're thinking? Does it really matter if we pray?
