The Irrevocable Covenant: Divine Promise Sealed by Oath

Paul appeals to human covenant-making to illuminate the nature of Yahweh's promise to Abraham. In earthly transactions, once a covenant is confirmed between two parties, neither can annul it or add fresh clauses—the agreement stands in all integrity. This human principle unveils a profound truth: what is true of a human covenant is essentially involved in the idea of a Divine covenant. Yahweh's covenant with Abraham is irreversible and irrevocable, established not merely by agreement but by oath.

The Judaistic theory attempted to supplement Abraham's covenant with the Law, but such addition would entirely abrogate the original promise. The new covenant consists in two words alone: Christ and faith. Christ is bestowed on Elohim's part; faith is required on ours. Christ is the matter of the covenant; faith is the consideration.

To Abraham and his seed—note the singular form denoting Christ's individuality, yet carrying collective force suggesting His representative character of human nature. The promise was twofold: temporal blessing through Jewish industry, wealth, and genius; spiritual blessing through Scripture, monotheism, and ultimately through the Messiah Himself. These are intermingled—the spiritual could not have come without the temporal, nor the temporal without the spiritual.

Some promises blossom hastily like the almond tree in earliest spring. Others resemble the mulberry tree—slow in putting forth leaves. The faithful man waiting for a delayed promise must simply wait: "If the vision tarry, wait for it till it come."
