Through Christ’s sacrifice we are all heirs of the promises of God. All that is required of us is faith; faith like that of Abraham. Romans 4:16 says, Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all. There is only one God and He is the father of all His creation. When Christ was sacrificed for our sin, we were all included in the inheritance of grace by God for each and every one of us. Just as Abraham’s faith guided him to believe before there was ever any laws or rituals, so does our faith (plus nothing else) lead us to believe in Christ’s saving grace.
