The Spoken word

Genesis 15:5-6
And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.
And he believed in the LORD; and he counted it to him for righteousness.

Galatians 3:6-7-8-9
Even as Abraham believed God, and it was accounted to him for righteousness.
Know ye therefore that they which are of faith, the same are the children of Abraham.
And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
So then they which be of faith are blessed with faithful Abraham.

Romans 4:20-21-22-23
He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
And being fully persuaded that, what he had promised, he was able also to perform.
And therefore it was imputed to him for righteousness.
Now it was not written for his sake alone, that it was imputed to him;

When we Believe God through his word Then God and imputes To our account as righteousness

Imputed righteousness
Imputed righteousness is a concept in Christian theology proposing that the “righteousness of Christ…is imputed to [believers]—that is, treated as if it were theirs through faith.” It is on the basis of Jesus’ righteousness that God accepts humans. This acceptance is also referred to as justification. The teaching of imputed righteousness is a signature doctrine of the Lutheran and Reformed traditions of Christianity.
