But, there was a problem. As of yet, there were no children who would inherit what God had promised. Practically speaking, Abram and Sarai were too old to have children. Nonetheless, Abram and Sarai acted in faith. Promises had been made and they believed. It would be a long time before the realization of those promises occurred.
To Abram and Sarai it must have seemed as if God had forgotten what He had said so long ago. Then the event of Genesis 15:1-21 occurred. While the promises listed above had already been given, the unconditional covenant between God and Abraham was not signed, sealed, and delivered until later.
Understandably, when God reiterated the promise He had already made, Abram asked how he could know for certain that these things will come to pass? After fulfilling God’s instructions, to slay animals and lay them opposite one another, A deep sleep came upon Abram. The blood from the sacrifices ran down between them forming a pool of blood. Taking the form of a smoking oven and a flaming torch, two times God himself walked the blood path ceiling the covenant the unconditional covenant He was making with Abram. The first time, God walked through the blood for Himself. The second time, for Abram. Why did he do this? It was because this covenant was not dependent upon Abram. It was dependent upon God alone. Fulfilling the obligations of this covenant felt solely on God.
Then he (Abram) believe in the Lord, and He (God) reckoned it to him (Abram) as righteousness. – Genesis 15:6
Abram was already acting in faith. In spite of his own sin, Abram’s salvation was already assured. It was 15 years between the time Abram and Sarai left Haran before God brought to pass what He had already promised. While God had already committed himself, the account of Genesis 15 was very important for Abram. God would never back out, He had sealed His covenant with blood.
Like he promised, Isaac was born and brought laughter to the house of Abram and Sarai when Abram was 100 years old.
For I am convinced that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the love of God, which is in Christ Jesus our Lord. – Romans 8:38-39
I trade great comfort in this passage. My grandfather once told me something that you have also probably heard. “A man is only as good as his word.” Once God has spoken and given His unconditional Word, nothing can ever change His mind. This s how I know that my eternal relationship with God is completely secure. I can now go about my business of making disciples with complete assurance that even when I stumble and fail, my eternal destiny is an absolute certainty.
Because of God’s Word, Abram could go forward in faith. Thanks to Abram’s example, I now understand what Abram understood.
