These beautiful words, "tender mercies" and "lovingkindness," may sound somewhat old-fashioned in today's sophisticated jargon, but the divine attributes they represent have been "ever of old" and will continue to characterize our tender and merciful, kind and loving God of all grace forever. Dropping them from our conversation (even in most newer translations of the Bible) is a sad loss that, to some degree, has impoverished our speech and, perhaps, our souls.
Note some of the rich scriptural testimonies associated with them: "|The Lord| redeemeth thy life from destruction; who crowneth thee with lovingkindness and tender mercies" (Psalm 103:4). "Withhold not thou thy tender mercies from me, O LORD: let thy lovingkindness and thy truth continually preserve me" (Psalm 40:11). "Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions" (Psalm 51:1). "Hear me, O LORD; for thy lovingkindness is good; turn unto me according to the multitude of thy tender mercies" (Psalm 69:16).
Other than Proverbs 12:10 ("the tender mercies of the wicked are cruel"), all the occurrences of these two terms, either alone or together, are applied by the translators only to the Lord, never to men (the Hebrew words are rendered by other words in the King James when applied to people). This is beautifully appropriate, for our gracious God is uniquely the God of love and mercy. In spite of the fact that none of us deserve His lovingkindness or tender mercy, "the LORD is gracious, and full of compassion; slow to anger, and of great mercy. The LORD is good to all: and his tender mercies are over all his works" (Psalm 145:8-9). HMM
