I can’t wrap my head around the reverse: if our works are literally nothing more than the manifestation of our faith and are entirely and utterly meaningless and worthless to our justification, why is so much ink spilled in the New Testament about how to behave as Christians? If it’s the natural result of true faith, shouldn’t it just appear on its own? Why do we need to be told?
Romans 10: 17, “So faith comes from hearing, and hearing through the word of Christ.” We receive faith through both Word and Spirit. We are built up and confirmed in our faith through the Word and the Spirit.
Faith “is the assurance of things hoped for, the conviction of things not seen” (Hebrews 11:1). How can we know what we have faith (assurance, conviction) in without first being taught or exposed to the message of Christ and the promises of God? How can we believe that we have been made holy, righteous and new creations if we never heard this preached in the power of the Spirit?
There is also a necessity to warn those who think they are justified when they are really not.
This is exactly my point. I can’t find a compelling argument from a sola fide advocate for why the way we behave matters. The only answer I can find that makes sense is that it proves our justification to ourselves, but I find that to be entirely uncompelling.
Because salvation is not only being declared righteous. It is being made alive when before we were dead in sin (Ephesians 2:1-5). It is being made a new creation–the old man is gone and the new man is here (2 Corinthians 5:17). It is becoming sons and daughters of God (Ephesians 1:5).
It is about life in the Spirit–and since we live in the Spirit we must walk in step with the Spirit (Galatians 5:25). We have not only been justified, but we have also been sanctified through the work of the Spirit and the belief in the truth (2 Thessalonians 2:13).
Because God is holy (and we are children of God), the Scriptures tell us to be holy in all we do (1 Peter 1:16). Because we were saved for the praise of his glory (Ephesians 1:12), and God will be glorified in us.
The different aspects/elements of salvation are typically expressed as the
ordo salutis or order of salvation. Protestants generally recognize the order or way of salvation to include the following:
Calling
Justification & Regeneration & Adoption
Sanctification (progressive, ongoing)
Glorification (after death)
If we’re justified by faith alone, why bother praising God? Seems like a waste of effort.
If we truly have faith, we will not only be justified but we will also be made new by our communion with Christ. Therefore, with a heart transformed by the love of Christ, we will give God glory because we love him, and we want other people to know him in the fullness of his truth and power.
In addition, God gets no glory out of his Son dying on a cross if all the people that are “saved” ultimately are unchanged in any meaningful way.
