Jews were keeping “the law” in order to get to heaven and that’s not how you get to heaven. The hope is in the promises that they inherited by Abraham. Abraham is an example of faith and patience in God’s promise. He waited 25 years from the time the promise was first made until Isaac, the promised son, was born. The Lord confirmed His oath to Abraham by swearing by Himself because He alone is beyond deceit. The two immutable things are God’s Word and God’s Oath. Since God does not lie and since He is all powerful, He will fulfill all His promises. This unchanging nature of God is the believers consolation and encouragement. The believer’s hope in Christ is secure, like an anchor.
