The Answer

The idea that there is a ‘head faith’ that is different from a ‘heart faith’ is a common error that undermines the simplicity of the Gospel. In the Bible, the Greek word for heart is ‘kardia,’ and it doesn’t refer to a feeling or a separate emotional chamber. The biblical ‘heart’ encompasses the mind, the will, the emotions, and the conscience. When Paul says in Romans 10:10, ‘For with the heart man believeth unto righteousness,’ he isn’t excluding the mind. In fact, Matthew 13:23 tells us that the one who received the seed on good ground is he who ‘heareth the word, and understandeth it.’ Understanding is a property of the heart.

When people use James 2:19 to scare you, they are ignoring the object of the belief. The demons believe that ‘there is one God.’ That is a fact of nature, but it is not the Gospel. The Gospel is the ‘power of God unto salvation’ (Romans 1:16). Believing the record that God gave of His Son—that He died for our sins and rose again—is not a ‘meritorious work’ that you have to perform with a certain level of emotional intensity. It is simply taking God at His word and certifying that He is not a liar (1 John 5:10).

Calvinism often redefines faith as a ‘virtuous work’ that man is too weak to do. They claim God must regenerate you before you can even believe. But the Bible presents a different order: the natural man, dead in sins, hears the message and believes it as a cry for deliverance. This ‘believing’ is the last act of the natural man before he is crucified with Christ and becomes a new creation. It isn’t a work; it’s a response to the truth.

The danger of the ‘head vs. heart’ distinction is that it forces you to look at yourself instead of at Christ. If you are told that ‘true’ faith must produce works to be real, you will spend your life checking your ‘fruit’ to see if you are really saved. But what happens during a season of pruning? In John 15, the Lord says He prunes the branches so they can bear more fruit. A pruned branch looks bare and dead for a season. If you are looking at your works for assurance during that time, you will lose your peace and conclude you never ‘really’ believed.

Assurance is not found in your performance; it is found in the message itself. Paul’s doctrine of justification is for ‘him that worketh not, but believeth on him that justifieth the ungodly’ (Romans 4:5). If you have believed the record that God gave of His Son, you have the witness in yourself. You don’t need to find a second, ‘deeper’ kind of faith to be secure. You are accepted in the Beloved because of what He did, not because of how well you feel you believed it.

Finally, we must recognize that James was writing to Jews in Jerusalem who were still very attached to the Law and the Temple. They did not yet have the full revelation of the ‘mystery’ given to Paul—the truth that Christ is our life and our sanctification. James uses the law as a mirror to expose the natural man’s spots. But we follow Paul’s mirror, where we behold the glory of the Lord and are transformed by the Spirit, not by our own efforts to make our faith ‘look’ real to others.
