A more accurate way of stating the truth is Justification by Grace through Faith, or simply (but can be confusingly), justification by faith.

The confusing part happens when the statement is taken out of context, as if FAITH alone can do the magic. Far from it! It is ALL GRACE from God that enables us to place our faith correctly on the Lord Jesus Christ and thereby to be justified.

See Romans 3:24, Ephesians 2:5,8 for the emphasis of God's grace. The rest of the verses try to dissociate from justification by deeds (or observing the OT laws). It is against the teaching of justification by deeds (observing the OT laws apart from faith) that justification by faith is emphasized. Note also that James emphasizes justification by faith and faith-enabled deeds. He is not against Paul at all.
