📖 Biblical Definition
A covenant keeper is one who holds the terms of a sworn covenant — and the LORD is praised throughout Scripture as the great Covenant Keeper. "Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations" (Deuteronomy 7:9); cf. 1 Kings 8:23; Nehemiah 1:5; 9:32; Daniel 9:4. The saint is called to mirror Him: "He that sweareth to his own hurt, and changeth not" (Psalm 15:4). Christian marriages, friendships, business dealings, and church memberships are tested by this character. The kingdom of God is built of covenant keepers — men whose word does not return void.
📜 Webster 1828 Definition

The LORD's identity in much of the Old Testament is summarized as covenant-keeper: He keeps with His people what He has sworn to them, even when they fail to keep with Him.
Christ's active obedience — His keeping the law on the saint's behalf — is, in part, a doctrine of His being the perfect covenant-keeper. The covenant Israel broke, He kept, on behalf of all whom the Father had given Him.

⚠️ Modern Corruption
Modern character culture often celebrates flexibility; Scripture honors the covenant keeper who keeps even when keeping costs.

Psalm 15:4's portrait of the man honored at the LORD's table is, in part, the covenant keeper: he that sweareth to his own hurt, and changeth not. He keeps when keeping is hard. Cultures rebuild on such people.
The household's daily covenants — marriage, parental, employment, ecclesial — rise or fall on this kind of keeping. The LORD keeps; His people are called to mirror Him.
