Charles H. Spurgeon on Psalms 116:9

I will walk before the Lord in the land of the living. This is the Psalmist's second resolution, to live as in the sight of God in the midst of the sons of men. By a man's walk is understood his way of life: some men live only as in the sight of their fellow men, having regard to human judgment and opinion; but the truly gracious man considers the presence of God, and acts under the influence of his all observing eye. "Thou God seest me" is a far better influence than "My master sees me." The life of faith, hope, holy fear, and true holiness is produced by a sense of living and walking before the Lord, and he who has been favoured with divine deliverances in answer to prayer finds his own experience the best reason for a holy life, and the best assistance to his endeavours. We know that God in a special manner is nigh unto his people: what manner of persons ought we to be in all holy conversation and godliness?
