Charles H. Spurgeon on Psalms 116:9

I will walk before the LORD in the land of the living, i.e., I shall pass the whole of my life under his fatherly care and protection. The prophet has regard to the custom of men, and chiefly of parents: for those who ardently love their children have them always in their thoughts and carry them there, never ceasing from care and anxiety about them, but being always attentive to their safety. Omnis enim in natis chari stat cura parentis. Children are, therefore, said to walk before and in the sight of their parents, because they have them as constant guardians of their health and safety. Thus also the godly in this life walk before God, that is to say, are defended by his care and protection. Mollerus.
