"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 are of the faith of Abraham. He is the father of us all" (Romans 4:16)
I find it amazing that the whole time, God's intention from the very beginning was to bestow grace upon mankind. This is truly the greatest story ever told. God didn't want to take any changes with his beloved creation, specifically humankind so he knew that to do this, salvation must be through grace.
The truth is, God always wanted relationship with us. His desired was a family. I Peter 1:20 tells us that Jesus was the spotless lamb chosen before the foundation of the world as the precious sacrifice for sin. His blood would be the atoning medium to bring us into right standing with God. Jesus was the promised Seed of Abraham. "The promises were spoken to Abraham and to his seed. The Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ." ( Galatians 3:16 )
So through Jesus, whether you are born into the natural line of Abraham or an heir to the promise through faith, the Bible says that Abraham is our father in the sight of God. God accomplished an amazing thing through the faith of one man. This man chose to believe God and because of it we share in the blessing that he obtained through faith. We choose to be a part of the family that God desired from the beginning and made possible through Jesus.
Today we can rest in the grace promised to Abraham, but provided through Jesus. It is by grace that we are saved and it has nothing to do with anything we can do. That my friend is wonderful news! That is why it is called the gospel or ‘almost too good to be true news!' Today I praise God that he has provided the means, the payment and the way to him through fulfillment of that promise.
