Evidence of faith is our actions (or works)
What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him?
For as the body without the spirit is dead, so faith without works is dead also.
What a man says is tested by what he does. A man may say he has faith, but merely saying he has faith will not profit unless accompanied by works which prove the reality of his faith.
Two example of people who demonstrated faith by works; Abraham and Rahab, prove that the mere profession of faith is not enough. There must be reality as proved by faith works. "As the body without the spirit is dead, so faith without works is dead also." In both cases the works prove the existence of faith in God, but they do so because of their special character. In neither case are they works of which the natural man could approve. Abraham is about to slay his son, and Rahab, a prostitute, to transfer her allegiance to God, and, as man would conclude, to betray her country. These are not "good works" as men speak. The practical life of the Christian is, indeed, to be marked by "good works", as the Apostle has already shown by exhorting believers to “visit the fatherless and widows in their affliction.” But the works that prove faith are so contrary to nature that, apart from faith, they would be condemned by every right-minded man. Thus, under the indication of God's will and in submission to it, the faith produces special works, and the works prove the faith.
