But thanks be to God, who gives us the victory through our Lord Jesus Christ. Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord. (1 Corinthians 15:57-58)
The resurrection of Jesus Christ brings spiritual victory over sin and death, to all who believe in Him. “But thanks be to God, who gives us the victory through our Lord Jesus Christ.” As we allow the Lord to be our guide through each day, He “leads us in triumph in Christ” (2 Corinthians 2:14). When this process is unfolding, an effective Christian life is developing, by the grace of God at work in us.
“Therefore, my beloved brethren, be steadfast.” It is the will of God that our lives be marked by steadfastness (constancy and stability). Paul rejoiced concerning fellow believers who manifested such attributes: “rejoicing to see your good order and the steadfastness of your faith in Christ” (Colossians 2:5). He later added that they were to be “rooted and built up in Him and established in the faith” (Colossians 2:7).
“Therefore, my beloved brethren, be…immovable.” Our heavenly Father also wants us to be “immovable” (firmly persistent, unable to be swayed). Paul was a good example of this. Although he faced many threatening difficulties, he professed “But none of these things move me” (Acts 20:24). When Paul wrote to the saints at Ephesus, he warned of another threat to spiritual persistency: “that we should no longer be children, tossed to and fro and carried about with every wind of doctrine” (Ephesians 4:14).
“Therefore, my beloved brethren, be…always abounding in the work of the Lord.” Our Lord wants us to be abundantly laboring with Him. This is one of the purposes of Jesus’ redemptive work for us: “Who gave Himself for us, that He might redeem us from every lawless deed and purify for Himself His own special people, zealous for good works” (Titus 2:14). Yes, living by grace will produce abounding good works. The glorious fact is that such labors are actually the Lord at work in and through us: “always abounding in the work of the Lord.” As the Lord sustains His work with us, we can grow in a certainty that this kind of laboring will be effective: “knowing that your labor is not in vain in the Lord.”
Note the key word that indicates the basis for all of these desirable traits: “Therefore.” This refers back to the resurrection victory provided by the Lord Jesus. In light of this victorious work of Christ on our behalf, anyone trusting in this reality will find these spiritual virtues developing in their lives, by the grace of God at work.
