We are encouraged to constantly strengthen our faith—the foundation of our relationship with God. Faith causes the motivation to follow God's way of life. Examining the details of how covenants cannot be annulled (Galatians), we investigate the details of the promise God made to Abraham. It was signed only by God, which showed it was entirely upheld by His grace. We see that the promise proceeds from simple, covering physical land and Abraham's immediate descendants to a group of nations and all the territory that they would possess, all the way up to eternal life granted to all those who follow the covenant through faith. The law preexisted the covenant, so Abraham was rewarded for keeping it, but some of the physical aspects were broken when the Israelites disobeyed. However, the spiritual part remains, and those who are the spiritual descendants of Abraham are promised eternal life. Jesus came down to earth and fulfilled the covenant perfectly, becoming High Priest wherein He reiterated the eternal covenant present with Abraham. We are to remain committed to faith and try to live up to it even though we will fall short.
