How plainly this last reference shows us that the whole of the covenant with Abraham, with all of its included promises, is purely Gospel. The oath backs the promise; but the oath gives consolation to us when fleeing for refuge to Christ; therefore the promise has reference to that which is to be gained in Christ. EVCO 109.2
This is also shown in the text which has so often been repeated, “If ye are Christ’s, then are ye Abraham’s seed, and heirs according to the promise.” The promise had nothing else in view but Christ and the blessings which are bestowed through His cross. EVCO 109.3
Thus it was that the Apostle Paul, whose determination was to know nothing but “Jesus Christ and Him crucified,” 11 Corinthians 2:2. could also say that he stood and was judged “for the hope of the promise made of God unto the fathers.” 2Acts 26:6. The “hope of the promise made of God unto the fathers,” is “the hope set before us” 3Hebrews 6:18. in Christ, and which is made “more abundantly” sure by the oath of God to Abraham. EVCO 109.4
