When answering some questions of a biblical nature, the questioner needs to harmonize, so to speak, a number of scriptures, much in the way readers of the four Gospels (yes, including John's Gospel) might harmonize an event in the life of Christ.
So it is with your question. Since searching for a "proof text" is likely not your MO, we need to look for a number of texts which together make a teaching clear, which in your case is the teaching that good works, or fruits, in the life of believers flow from faith. I believe they do.
First, the apostle Paul makes one thing perfectly clear:
. . . and whatever is not from faith is sin (Romans 14:23b NASB).
The verse, of course, is within the context of a chapter concerning "Principles of Conscience" (as the NASB puts it). In the chapter, Paul differentiates between two types of Christians: First, is the brother (or sister) who is "weak in faith," which is not necessarily a description of the person's Christian life in general but the person's Christian life specifically regarding what could be called "grey issues."
In Paul's day, a divisive grey issue involved the eating of meat which had been sacrificed to idols. Some believers did not have faith that eating this meat was God's will for them; consequently, they refrained from doing so. Some other believers, like Paul himself, did not have a scruple about eating this meat, since he and they knew--or had the faith that
. . . nothing in unclean in itself (14:14a).
He goes on to say in the same verse, however, that
. . . but to him who thinks anything to be unclean, to him it is unclean (v.14b, my emphasis).
Just to be clear, thinking something is or is not clean is a matter of faith (again, see 14:1). A Christian who by faith refuses to eat meat sacrificed to idols is approved by God, as is the Christian who by faith partakes of meat sacrificed to idols is approved by God. Both actions are in the category of "good deeds" or "good works," but both are expressed in different ways.
Parenthetically, a Christian "ministry" in the area of, say, teaching or preaching the Word, is also expressed in different ways from person to person. [Actually, the same could be said of virtually any one of the "spirituals," and I say "spirituals" since most Bible versions insert the word gifts after the word spiritual, so we often refer to the "spirituals" as "spiritual gifts." In my opinion there is nothing wrong with this.]
Some believers might have a niche in teaching youngsters, or teens, or college-and-career folks, or adults with a variety of SMQs (spiritual maturity quotients). The teacher, himself or herself, is still a gift to the church (as is the apostle, prophet, and evangelist--Ephesians 4), and God expects his or her teaching to proceed from faith and to be exercised in the strength which only God can supply (1 Peter 4:11).
Second, if good deeds which do not proceed from faith are tantamount to sin (again, Romans 14:23b), then the faithless Christian is not bearing the kind of fruit which God desires for him or her and is not truly bearing fruit. To bear fruit consistently and in a manner which passes God's muster, or judgment (Romans 12:10-12 ff.), a believer must be acting in faith.
This action in faith applies not just to matters of conscience or scruples; rather, it applies to every aspect of fruit bearing. Abiding by faith in Christ the true vine is the only way to bear fruit which remains and will be judged acceptable by God (John 15:1-17, especially vv.5-8). The word faith may not be used in John Chapter 15, but it is certainly a fundamental aspect of fruit bearing.
The biblical teaching on fruit bearing and its relationship to matters of faith, then, is a concatenation of at least two (and quite likely more than two) teachings; namely, works which proceed from faith are not sin, and those works are fruits which bring glory to God, stimulate spiritual growth, and will be rewarded by God.
In conclusion, Christians who are maturing in their Christian walk and in their sanctification are exercising their faith in ways which bear much fruit, and by doing so are approved by God and rewarded handsomely in this life, as well as in the life to come (see Romans 14:10-12 and 2 Corinthians 5:6-10, where in the former reference Paul says, "for we walk by faith, not by sight," and we "will be recompensed [at the judgment seat of Christ] for [our] deeds in the body, according to what [we] have done, whether good or bad").
