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 15:58, NKJV)
The Corinthian church had problems. Every church does. That’s because every church is composed of sinners, redeemed by the blood of the Lamb. We struggle with temptations and sins, with our faith and our failings. Christians in every congregation must address weakness and weariness, responsibilities and relationships, and much more (Rom. 12:3-21). Paul exhorted the Corinthian brethren to remain true to the Lord as they faced spiritual challenges from within themselves and from the world without. Like them, we must be “steadfast” (settled, firmly situated) in our faith. The roots of our faith must run deep within us, anchored by the word of God, in order for spiritual growth to flourish. By building our personal faith we become stabilized, standing firmly in the faith, and able to resist the enticements of sin (Col. 2:7; Jas. 1:14). By such steadfastness we become “immovable” (unmoved) against the external forces of error and evil (Col. 2:8; Eph. 4:14-16; 1 Pet. 4:1-3). (Remember, the devil is always probing for our vulnerabilities, 1 Pet. 5:8.) Spiritual stability enlivens our duty (“work”) in the Lord with purpose, devotion, endurance, and fullness. Our incentive to fulfill our duty to the Lord is clear – our labor is not useless in the Lord. A full, everlasting harvest awaits the faithful (Gal. 6:7-8).
