The Belgic Confession (1561) contains no less than two (2) articles dealing with the topic of justification. The first of these is Article 22 (“Our Justification Through Faith in Jesus Christ”), which is as follows:
“We believe that, to attain the true knowledge of this great mystery, the Holy Spirit kindles in our hearts an upright faith, which embraces Jesus Christ with all His merits, appropriates Him, and seeks nothing more besides Him. For it must needs follow, either that all things which are requisite to our salvation are not in
Jesus Christ, or if all things are in Him, that then those who possess Jesus Christ through faith have complete salvation in Him. Therefore, for any to assert that Christ is not sufficient, but that something more is required besides Him, would be too gross a blasphemy; for hence it would follow that Christ was but half a Savior.
“Therefore we justly say with Paul, that we are justified by faith alone, or by faith apart from works. However, to speak more clearly, we do not mean that faith itself justifies us, for it is only an instrument with which we embrace Christ our righteousness. But Jesus Christ, imputing to us all His merits, and so many holy works which He has done for us and in our stead, is our righteousness. And faith is an instrument that keeps us in communion with Him in all His benefits, which, when they become ours, are more than sufficient to acquit us of our sins.”
First note the source of justifying faith – it is the work of the Holy Spirit who “kindles in our hearts an upright faith.” No doubt this is what Paul means in Ephesians 2:8 when he tells us that we have been saved by grace through faith, and then adds, “And this is not your own doing; it is the gift of God” (ESV). Even our very faith in Christ is the gift of God! Left to ourselves, none of us would ever believe in Christ for salvation.
Second, note the object (so to speak) of justifying faith – “Jesus Christ with all His merits.” In other words, by faith we embrace or receive Christ Himself (His person) and all of His merits (i.e. His work – all that He has done for our salvation). In his exposition of the Belgic Confession (With Heart and Mouth), Daniel Hyde writes,
“By faith we look outside of our merit and ourselves. Like beggars, we receive only that which is given by another. What is given is the only One who has done anything good in the eyes of God, the only One who merited, that is, earned, and therefore was rewarded with righteousness to give to his people on the basis of his obedience to the law.” (p.294-295)
Notice thirdly the “instrument” of our justification – faith alone. We must be careful to understand that it is not faith of itself that justifies us, as if it were somehow inherently meritorious before God, but rather that faith itself is the only instrument by which we receive Christ and all of the benefits of redemption. Faith is “only an instrument with which we embrace Christ our righteousness.” Christ Himself is our righteousness. Christ Himself justifies us and saves us from our sins.
Faith alone is the instrument of our justification, for it is through faith alone that we look outside of ourselves and “embrace Christ our righteousness,” and so are justified in Him!
