 Prayer gives us tremendous focus, wisdom, and complete peace of mind. Through prayer, we form a strong bond with the Lord. And when we pray often, as we should, we find Jesus is in our hearts, making each day easy to get through and letting us live at ease, knowing that no matter what we are dealing with, the Lord will give us the strength to get through it. So yes, we're going to have doubts. That's just what humans do.
