Thoughts on Prayer by Charles Spurgeon:
Childlike confidence makes us pray as none else can. It causes a man to pray for great things that he would never have asked for if he had not learned this confidence. It also causes him to pray for little things that many people are afraid to ask for, because they have not yet felt toward God the confidence of children. I have often felt that it requires more confidence in God to pray to Him about a little thing than about great things. We imagine that our great things are somehow worthy of God’s attention, though in truth they are little enough to Him. And then we think that our little things must be so insignificant that it is an insult to bring them before Him.
