TSK · Genesis 15:6

For what does the scripture say?“Abraham believed God, and it was credited to him as righteousness.”

And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised, so that he would become the father of all those who believe but have never been circumcised, that they too could have righteousness credited to them.

In other words, in Christ God was reconciling the world to himself, not counting people’s trespasses against them, and he has given us the message of reconciliation.

By faith Abraham obeyed when he was called to go out to a place he would later receive as an inheritance, and he went out without understanding where he was going.
