God specifically identified his son, since he had two at that time. He did not challenge God concerning His promise of making his descendants a great nation. Instead, he took the step of faith and trusted God to fulfill His promise to him in some way or other. His obedience sprouting from faith brought the belief of the resurrection of his son, for he reasoned that God was able to raise [him] up even from among the dead. Indeed in the sense that Isaac was figuratively dead, he did receive him back from the dead (Hebrew 11:19).
Abraham was faithful even unto death of his son. Through the righteous seed of Abraham, God brought His Son to the world. So Abraham withstood the test of faith and as a result the Lord said, “Since you have done this and have not withheld or begrudged you son, your only son, in blessing I will bless you and in multiplying I will multiply your descendants like the stars of the heavens and like the sand of the seashore. And your Seed will possess the gate of His enemies, and in your Seed (Yahshua) shall all the nations of the earth be blessed, and [by Him] bless themselves, because you have heard and obeyed My voice (v17-18). Here I am!
Job, on the journey of testing of his faith, said, “though He slay me ,[ yet will I wait for and trust Him I will wait on Him] (13:15); make me recognize and know my transgression and my sin (13:23b); For I know that my Redeemer and vindicator lives, and at last He will stand upon the earth, and after my skin, even this body, has been destroyed, then from my flesh or without it I shall see God. . .And my eyes shall behold Him, and not as a stranger! (Job 19;25-27). I had heard of You [only] by the hearing of the ear, but now my eye sees You. Therefore I loathe [my words] and abhor myself and repent in dust and ashes” (42:5-6).
How do we know if we have passed the test of faith? By endurance, perseverance and patience; by looking back and being able to say, “I have fought the good fight, I have finished the race, and I have kept the faith. Henceforth there is laid up for me the [victor’s] crown of righteousness, which the Lord the righteous Judge, will award to me and recompense me on that day” (II Timothy 4:7-8).
When we pass through the valley of sufferings or through the testing of our faith, let’s remember the words of the apostle Peter, “Be exceedingly glad on this account, though now for a little while you may be distressed by trials, and suffer temptation, so that [the genuineness] of your faith may be tested, which is infinitely more precious than the perishable gold which is tested and purified by fire to redound to praise and glory and honor when Yahshua Messiah is revealed” (I Peter 1:7). In comparison with eternity, our suffering will be only for a short time, for “the sufferings of this present time are not worth being compared with the glory that is about to be revealed to us and in us and for us and conferred on us” (Rom. 8:18)! Praise the Lord that His work of sanctification carries a weight of eternal value in us and for us and His promise is that nothing can separate us from His love! Our sufferings then should lead us to Him, and not away from Him.
