I. The smile of God has its moving cause in the infinite heart of God.
II. The smile of God comes from His heart, and thus from His love and His blessedness.
III. The smile of God is essential to us, and it alone is sufficient for us. With the smile of man and without the smile of God there is neither well-being nor welldoing. With the smile of God and without the smile of man there must be prosperity, and there may be peace and joy.
IV. The smile of God is sorely missed when, having been found, it is lost. The loss of that smile was the occasion of the Psalm before us being written. Child of God, disciple of Jesus Christ, afflicted one, but comforted, recovered backslider, labourer in God's vineyard, and ye who abide in Jesus, God smiles upon you. Every good gift, every gracious work, every merciful dealing with us, every prevention of mischief to us, every word of promise, is a smile of God. Above all, the face of Jesus is God's perfect and infinite smile.
S. Martin, Comfort in Trouble,p. 58.
