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, that I may make my covenant between me and you, and may multiply you greatly.” (Genesis 17:1-2)
Thirteen years after the birth of Ismael, God approached Abram in a series of statements defining the covenant he was making with Abram and his family. God introduced himself as God Almighty (El Shaddai, meaning all powerful). He challenged Abram to be faithful (walk before me) and faultless (be blameless). In previous promises, God indicated what he would do. In this case the covenant is in two parts, what Abram needed to do and what God would do. The Lord promised that the covenant will be in place if Abram, his descendants are blameless.
As part of the Covenant, God changed Abram’s name to Abraham, a father to the nations including those who are not his biological children. Not only does the covenant cover offspring but the land of Canaan. Further, he instructed Abraham to circumcise all male members of his household at eight days old as a sign of the covenant. Circumcision was to be without regard to race or lineage. Those not circumcised will be cut off from the covenant.
The Lord also changed Sarai’s name to Sarah and promised she would bear a son in a year and that kings of the nations would come from her. Abraham laughed, questioning how that could happen at his age and suggested Ismael be the promised son. God told him his son would be Isaac and the covenant would apply to him and his offspring but not to Ishmael. Abraham then followed God instructions and circumcised all the males in his household.
When we accept the Lord’s offer of salvation and allow the Holy Spirit to work in and through us (becoming faithful and blameless), we enjoy his blessing.
God blesses the faithful and blameless.
