What does the Bible say about covenant love?

Covenant love, as depicted in 1 Samuel 18:1-4, illustrates a binding relationship characterized by commitment and sacrifice. This love is profoundly illustrated by the bond between Jonathan and David, where Jonathan willingly yields his royal privileges to David, showing his deep loyalty and submission to God's will. This act of self-denial mirrors the covenant love Christ has for His people—marked by His supreme sacrifice, as He laid down His life for sinners, ensuring the eternal bond between Himself and those whom He loves. Scripture reinforces this concept, highlighting God's steadfast nature; as noted in Deuteronomy 7:9, He is the faithful God who keeps covenant and mercy. Thus, covenant love endures beyond human fickleness, rooted in divine promise.
