If you are a Christian, your life will produce spiritual fruit.
If you want to enjoy assurance of salvation in all its richness, you need to faithfully pursue all the virtues we have been studying this past week. The reason is simple—they produce fruit in the Christian life, and nothing is a better indicator of true salvation than that. It was the criterion Christ used to distinguish between the true and false believer (Matt. 7:15-20).
The reasonable question that ought to arise next is, what is fruit? The New Testament says it encompasses many righteous activities. Paul says winning souls to Christ is fruit (Rom. 1:13). The apostle calls the house of Stephanas “the first fruits of Achaia” (1 Cor. 16:15). In Philippians 4:17 Paul refers to money given in the support of ministry as fruit. The writer of Hebrews says praise is the fruit of our lips (Heb. 13:15). The act of praying is also a spiritual fruit.
Behind every one of those righteous actions is the right attitude, because “the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control” (Gal. 5:22-23). If you act without a godly attitude, it is only legalism, not genuine spiritual fruit.
All the Spirit-endowed virtues, actions, and attitudes we have discussed, if they are in your life, will assure you that you’ll be “neither useless nor unfruitful.” “Useless” is also used in James 2:20 in relation to dead faith. If you incorporate into your life the virtues of 2 Peter 1:5-7, your faith will not be dead or ineffective.
“Unfruitful” is also used in Matthew 13:22 of the person with a weedy heart and of false, apostate teachers in Jude 12. When you don’t live a virtuous life, you are the same as an apostate or a worldly hanger-on in the church.
“In the true knowledge of our Lord Jesus Christ” refers to true believers, those who possess truth as opposed to error. Because you know Christ, you have the ability to live a virtuous life (see Eph. 1:3; 2 Peter 1:3). When you do, God will give you true assurance.
Suggestions for Prayer
Pray that God would strengthen any of the virtues that are weak in your life.
