Real faith is different from pseudo-faith. Mental assent is not enough. Even the demons believe there is one God. It is necessary to place your trust in God. That is biblical faith.James uses the word 'justification' in a different context that Paul does. Justification before God is faith apart from works just as Paul taught. Justification before people as James taught, is different because people can't see into the heart as God can. Godly deeds justify believers to a watching world.
