“This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us” (1 John 3:23).
Federal Visionists love this verse because they think that we are “commanded” to “believe.” However, this turns faith into a work, which is a standard Pelagian mistake.
The Reformed faith has always insisted that faith is a resting, relaxing, and reposing in the finished work of Christ. In no way is faith a work. In no way is faith obeying a commandment.
If we ever view belief or faith as a commandment, then we are going to turn faith into obedience, which is a work. Faith is in no sense a work. Faith occasionally performs works, but faith is not a work itself.
Those who claim that faith is a commandment to be obeyed are preaching a different gospel, which is no gospel at all.
