But God gives us his glorious promise to strengthen us to keep on enduring until his promise is fulfilled. So it remains for us to have faith in His promise, just as Abraham of ancient time did. God Almighty can supply us the needed faith and power of endurance. We have His word for it in Romans 15:4, 5:

Now may the God who supplies endurance and comfort grant you to have among yourselves the same mental attitude that Christ Jesus had [not pleasing himself, but pleasing God].”

 3. (a) How did Christ’s mental attitude function, leading to what reward? (b) In consideration of what on our part shall we be rewarded with the fulfillment of God’s promise?

³ The mental attitude of Christ Jesus leaned ever toward doing the will of God his heavenly Father. His mental attitude inclined him to endure whatever befell him for doing God’s will. Consequently he never wavered. Never did he shrink back. The prospect of enduring a sacrificial death as foretold for him in the Scriptures “written aforetime” did not turn him aside from doing his Father’s will. For enduring a martyr’s death he was rewarded with a resurrection to heavenly life. Thus he endured until the fulfillment of God’s promise to him, even though he knew that this required God to perform his mightiest act in his behalf. (Eph. 1:19-21) In harmony with Christ’s own case, the apostle Paul prayed for God Almighty to supply endurance to us. (Rom. 15:5) This prayer will never fail as long as we persevere in doing God’s will. As a reward for our enduring down to the finish we shall receive the gladdening fulfillment of God’s promise to us.
