Charles H. Spurgeon on Psalms 91:14

Because he hath set his love upon me. Vulg. Because he hath hoped in me. Whatever is to be done, whatever is to be declined, whatever is to be endured, whatever is to be chosen, Thou O Lord art my hope. This is the only cause of all my promises, this the sole reason of my expectation. Let another pretend to merit, let him boast that he bears the burden and heat of the day, let him say that he fasts twice on the Sabbath, let him finally glory that he is not as other men; for me it is good to cleave unto God, to place my hope in the Lord God. Let others hope in other things, one in his knowledge of letters, another in his worldly wisdom, one in his nobility, one in his dignity, another in some other vanity, for thy sake I have made all things loss, and count them but dung; since Thou, Lord, art my hope. Bernard, quoted by Le Blanc.

Verse 14 (.first clause). As there is a because and a therefore in the process of the law, in concluding death for sin, so there is a because and a therefore in the process of grace, and of the gospel, which doth reason from one grace given to infer another grace to be given, even grace for grace; and such is this here: Because he hath set his love upon me, therefore will I deliver him. David Dickson.
