The Bible speaks of the “fruit of the Spirit” in the singular to show that it is one unified work of the Holy Spirit expressed in many righteous qualities such as love, joy, peace, and self-control (Galatians 5:22–23). Paul contrasts this Spirit-produced fruit with the “works of the flesh,” which are many and fragmented, showing the difference between the transformation God produces and human effort (Galatians 5:19–23). Jesus explains that fruit always reveals its source: a good tree bears good fruit and a bad tree bears bad fruit (Matthew 7:17–18). He also teaches that abiding in Him is the only way to bear lasting fruit, since apart from Him we can do nothing (John 15:4–5). The Old Testament also reveals this truth by describing the righteous as trees planted by streams of water who bear fruit in season (Psalm 1:1–3). This means spiritual fruit is not a list of separate achievements but the natural result of a life rooted in God and empowered by His Spirit. Every believer’s growth in righteousness flows from one source—abiding in Christ through the Holy Spirit who transforms the heart (Romans 8:9).
Christians are counted
righteous when saved (Romans 4:5), though they do not actually become actively and fully righteous! Conversion
begins the lifelong process of God transforming us from unrighteous to being conformed to the image of His Son (Romans 8:29). He does that through the Holy Spirit who
lives within us and changes us, as well as by us actively walking in the Spirit
(Galatians 5:16) and abiding in Christ (John 15:4–5).
Because the
Spirit changes our hearts and minds, and thus our view of the world, believers
start demonstrating the fruit of righteousness (singular) in multiple areas.
Those many differences come from the singular change of us being made more
righteous.
Because the
Spirit is within all believers (Romans 8:9) and because His goal is our sanctification (1 Thessalonians 4:3), all believers will have evidence of righteousness in their lives, though the evidence may vary from one believer to another. Some seasons will also show more clear evidence of fruit than others. The point is that there is fruit. However, regardless of the inconsistencies,
James warned that if there’s zero evidence of fruit, that’s a warning
sign of a dead (false) faith (James 2:17).
So, fruit is both
expected and necessary. How can we cultivate such fruit in our lives? We start
by acknowledging that apart from the Spirit and Jesus’ changing work, we can do
nothing. We then faithfully abide in Him, reading God’s Word, going to church, fellowshipping with
other believers, and serving in the body of Christ. As we do all of that, we are striving to live righteously,
with the result that, with the Spirit’s guidance, such obedience is making us
more righteous.
