Let thy tender mercies come unto me,.... See Gill on Psa 119:41; that I may live; not merely corporeally; though corporeal life is a grant and favour, and the continuance of it; it is owing to the tender mercies of God that men are not consumed: but spiritually; the first principle of spiritual life is from the rich mercy and great love of God; his time of love is a time of life. Here it seems to design the lively exercise of grace, which is influenced, animated, and quickened by the love of God, as faith, hope, and love; or a living comfortably: without the love of God, and a view of it, saints look upon themselves as dead men, forgotten as they are, free among the dead, that are remembered no more; but in the favour of God is life; let but that be shown, let the tender mercies of God come in full flow into the soul, and it will be revived, and live comfortably; and such also shall live eternally, as the fruit and effect of the same love and favour; for thy law is my delight; or "delights" (u); what he exceedingly delighted in, after the inward man, and yet could not live by it, without the mercy, love, and grace of God; see Psa 119:24.
