Because we live in a "contract world," we often treat God like a "contract God." We feel that if we have a bad week or a season of doubt, the deal is off. We live in fear that we’ve broken the contract and God is going to "evict" us from His grace. We default to “earning” rather than “receiving.” So we wonder, “Am I really right with God?” “Can I truly trust in His saving promises?” “What if I fail or doubt or wander astray?” We need assurances. Genesis 15 gives us assurance. It shows us that God Himself secures His saving promises. In Genesis 15, Moses recorded how the LORD reassured Abram by declaring him righteous through faith and by unilaterally making a covenant in blood, guaranteeing the future fulfillment of His redemptive promises.
