He was fully convinced that what God has promised, He also is able to do. That is why “it was credited to him as righteousness.” Now not only for his sake was it written that it was credited to him, but for our sake as well. It is credited to us as those who trust in Him who raised Yeshua our Lord from the dead. He was handed over for our transgressions and raised up for the sake of setting us right.
There is only one way to enter into heaven, trust God, just as Abraham did. We must trust in everything God has done for us including sacrificing His son Yeshua for all of our sins. There is no other way.
