And because ye are sons, God hath sent forth the Spirit of His Son into your hearts, crying, Abba, Father. -Galatians 4:6

When I was racked some months ago with pain, to an extreme degree, so that I could no longer bear it without crying out, I asked all to go from the room, and leave me alone; and then I had nothing I could say to God but this, “Thou art my Father and I am Thy child; and Thou, as a Father, art tender and full of mercy. I could not bear to see my child suffer as Thou makest me suffer, and if I saw him tormented as I am now, I would do what I ‘could to help him, and put my arms under him to sustain him. Wilt Thou hide Thy face from me, my Father? Wilt Thou still lay on a heavy hand, and not give me a smile from Thy countenance?” I held the Lord to that. I talked to Him as Luther would have done, and pleaded His Fatherhood in right down earnest. “Like as a father pitieth his children, even so the Lord pitieth them that fear Him.” If He be a Father, let Him show Himself a Father-so I pleaded, and I ventured to say, when I was quiet, and they came back who watched me: “I shall never have such pain again from this moment, for God has heard my prayer.” I bless God that ease came and the racking pain never returned. Faith mastered the pain by laying hold upon God in His own revealed character, that character in which in our darkest hour we are best able to appreciate Him. I think that is why that prayer, “Our Father which art in heaven,” is given to us, because, when we are lowest, we can still say, “Our Father,” and when it is very dark, and we are very weak, our childlike appeal can go up, “Father, help me! Father rescue me!” ~ C.H. Spurgeon
