1 When Abram was ninety-nine years old the LORD appeared to Abram and said to him, “I am God Almighty; walk before me, and be blameless, 2 that I may make my covenant between me and you, and may multiply you greatly.” —Genesis 17:1–2
When the covenant was cut with Abram in Genesis 15, God walked it alone. Concerning the covenant promises, Abram had asked God, “How shall I know…?” (Genesis 15:8). God instructed Abram to bring him several animals. Abram cut them in half and laid the pieces opposite one another. Manifest as something like a smoking fire pot and a flaming torch, God passes between the pieces. Normally, when a covenant was made, both parties would walk through the pieces, pledging covenant loyalty and invoking a curse on themselves should they fail to keep covenant. But God walked it alone.
In Genesis 12, Abram walks, leaving Haran to journey to the land God would show him. In Genesis 17, Abraham walks before God, keeping covenant, circumcising all the males in his household. Between Abraham’s two walkings, God walks it alone. and it is there, in Genesis 15, where Abram does nothing but believe God’s word, that we are told, “he believed the LORD, and he counted it to him as righteousness” (Genesis 15:6).
Paul makes a big deal of this order in Romans 4 telling us that Abraham “received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well, and to make him the father of the circumcised who are not merely circumcised but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised” (Romans 4:11–12; emphasis mine). The order is critical. It is an order one must keep in mind when they read “walk before me, and be blameless, that I may make my covenant between me and you, and may multiply you greatly” (Genesis 17:1–2; emphasis mine).
Before the sign, the signified. God circumcises before Abraham does. There is a circumcision without which circumcision means nothing. Because God walked it alone, Abraham walks. His covenant faithfulness ensures ours.
Saints, Jesus walked it alone. He walked before God all His days to be your righteousness. He walked to the cross to bear the wrath of the Almighty for your sin. He walked out of the tomb conquering death and Satan. Because He walked it alone, you walk in Him. Because He died and rose, you have died and risen and may be baptized. Because He circumcised your heart, you may love. Because of His covenant faithfulness you may keep covenant.
