What is meant by being a fruitful Christian?

from the old testament

• Being a fruitful Christian is specifically addressed in the New Testament.

from the new testament

• In Scripture, fruit is a metaphor used to describe the outward demonstration of one's inward disposition. Our fruit can be either good or bad. Naturally, all people produce bad fruit (Matthew 15:18–20).
• Good fruit cannot be judged on external acts. If that were the case, then the Pharisees would have been the most fruitful. Instead, Jesus called them white-washed tombs because although they appeared good on the outside, inside they were rotten (Matthew 23:27–28). Instead of being motivated by love for God, they were motivated by self-righteousness (Matthew 23:5–7). They bore bad fruit disguised as good fruit.
• As born again Christians, we can be fruitful by seeking to share the good news of salvation and disciple others in the faith (Matthew 28:18–20).
• It is important to understand what it truly means to be a Christian in order to know how to bear good fruit. God's word teaches that true Christians are those who are born again in Him (John 3:3) because of belief in Jesus Christ. After belief in Christ, we are then made into new creations in Christ—indwelt and empowered by the Holy Spirit.
• We can bear spiritual fruit by loving others with the love of Christ (John 13:34–35).
• Part of living a fruitful life for God is seeking to know Him and to do the things which please Him (John 15:1–12). We know we can bear no true fruit apart from Him.
• We can use our spiritual gifts to build up the body of Christ (1 Corinthians 12). As such, we can produce good fruit and encourage others to do the same.
• The contrast between the fruit produced by sin and the fruit of the Holy Spirit produced in the life of a Christian is clearly set forth in Galatians 5:19–24. Those who belong to Jesus Christ produce the fruit of the Holy Spirit.
• When given the opportunity, we should seek to produce spiritual fruit by doing good to everyone (Galatians 6:9–10).
• Our bad behavior/fruit is a natural result of being born with bad hearts (Ephesians 2:3).
• As Christians, we can more easily forgive (Ephesians 4:32). This can produce good fruit in our lives while also making a godly impact on others’ lives.
• It is crucial to realize that being fruitful is not something that is accomplished by mere human willpower. It is done only by the power of God and His Holy Spirit working in and through us in Christ. Being fruitful is a work of God's grace (Philippians 2:13).
• Unlike the world that always has something to complain about, we should seek to be grateful for Him and give praise to Him (Colossians 3:15). As such, we are pursuing a spiritually fruitful life characterized by thanksgiving to God.
• Living out a fruitful life looks like seeking to do all things for God's glory (Colossians 3:17).
• In 2 Peter 1:5-8, the apostle Peter states, "For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love. For if these qualities are yours and are increasing, they keep you from being ineffective or unfruitful in the knowledge of our Lord Jesus Christ." It is not actions, but qualities, that must have the priority in our life. God first transforms our inner being, which then results in our bearing good fruit outwardly.
• In humility, we should confess our sins to God and pray for His continual work in our lives (1 John 1:9) as we seek to bear spiritual fruit for His glory alone.

implications for today

Being a fruitful Christian is not accomplished by checking off a "to do" list but by having our essential being and character changed, renewed, and progressively conformed to the image and likeness of Christ (Romans 12:2; 2 Corinthians 3:18). Good fruit is seen in a change in our disposition, attitudes, affections, and actions. Those sins that we formerly loved become loathsome to us (Romans 6:21). To be fruitful means to follow Christ. To love what He loves. To do what He commands from a loving motive and with a joyful spirit. This obedience is both predestined and empowered by God which removes any grounds for boasting in how fruitful our lives or ministries become (Ephesians 2:10; 1 Corinthians 1:28–31). It is by God's grace and our abiding in Christ that we produce good fruit (John 15:4–5). The fruit is good because God is good and we ascribe all the glory to Him for it (Philippians 1:11).
