Genesis 15:6 NIV

Hebrews 11:8 NIV
By faith Abraham, when called to go to a place he would later receive as his inheritance, obeyed and went, even though he did not know where he was going.

James 2:23 NIV
And the scripture was fulfilled that says, “Abraham believed God, and it was credited to him as righteousness,” and he was called God’s friend.

Romans 4:11 NIV
And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them.

Romans 4:3-6 NIV
What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.” Now to the one who works, wages are not credited as a gift but as an obligation. However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness. David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works:

Romans 4:9 NIV
Is this blessedness only for the circumcised, or also for the uncircumcised? We have been saying that Abraham’s faith was credited to him as righteousness.
