Catholic interpretation of Romans

Can anyone provide an interpretation of Romans 4:5 and how it relates to justification / sanctification by faith and / or works?

1What then shall we say that Abraham, our forefather, discovered in this matter? 2If, in fact, Abraham was justified by works, he had something to boast about—but not before God. 3What does the Scripture say? “Abraham believed God, and it was credited to him as righteousness.”[a]
**4Now when a man works, his wages are not credited to him as a gift, but as an obligation. 5However, to the man who does not work but trusts God who justifies the wicked, his faith is credited as righteousness. 6David says the same thing when he speaks of the blessedness of the man to whom God credits righteousness apart from works:
7"Blessed are they
whose transgressions are forgiven,
whose sins are covered.
8Blessed is the man
whose sin the Lord will never count against him."

Thanks.**

It is the presence of sanctifying grace in our souls that justifies us. We receive this grace as a gift in Baptism. We do not have to do “works” in order to merit it.

CCC #1266 The Most Holy Trinity gives the baptized sanctifying grace, the grace of justification: …,…

What are your works and why do you do them? Abraham’s Faith and his Actions (according to James) were credited as Righteousness. Why? Because he offered up his own son in obedience to God.

Where is your heart when you do anything out of obedience to God?
