17 You therefore, beloved, since you know this beforehand, beware lest you also fall from your own steadfastness, being led away with the error of the wicked; 18 but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen (2 Peter 3:17–18, NKJV).
It is essential to see the interdependent relationship between grace and knowledge in today’s passage. Peter’s summary draws attention to the truth his audience already knew (“since you know this beforehand,” v. 17) and warns against falling from their steadfast faith, led away by the error of the lawless. Growing in the “grace and knowledge of our Lord” protects us from being led away by error from the Lord (v. 18). Yes, God’s grace is greater than sin. But we cannot “continue in sin that grace may abound” (Rom. 5:20-6:1). (Grace is not a license to sin by teaching and following error.) Growing in grace is explained in Titus 2:11-14 as denying sin and living “soberly, righteously, and godly in the present age.” So, growing in grace requires us to increase in our knowledge of “the gospel of the grace of God” (Acts 20:24). Good fruit results when we hear, know, and follow “the grace of God in truth” (Col. 1:5-6, 9-11). The gospel is “the word of His grace” that strengthens us and grants us our eternal inheritance (Acts 20:32). Therefore, we are strengthened by God’s grace as we grow in our knowledge of His word (2 Tim. 2:1-2). Grace and knowledge are not opponents. They work together, bringing glory to our Lord and Savior Jesus Christ as they equip us to share in His glory (Col. 3:4).
If the foundations are destroyed, what can the righteous do? (Psalm 11:3, NKJV)
The foundations of our society are cracked. Decades of denying the existence of God and His truth, of sanctioning the killing innocent, unborn life, of oppression of our neighbors to get ahead, and of rejecting the fundamental truths of morality and marriage – all these and more can tempt us to despair of hope and remedy. Through David, God gives us answers that look above the moment and beyond the horizon of hurt and horror. When the foundations are destroyed, the righteous can 1) Keep their trust in the Lord God (Psa. 11:1-2). Corrective truth comes from God, not humans (Jer. 10:23). He protects us from an eternal perspective that we must foster that grounds us in times of trouble. 2) Remember God has not moved (Psa. 11:4). He remains enthroned in heaven; His sovereignty secures our faith and assures us His purposes prevail. 3) Know God sees and investigates every person and judges between the good and the evil (Psa. 11:4-6). The wicked do not escape His gaze and cannot hide from His justice (Rev. 6:12-17). 4) Know God is righteous, and He loves righteousness (Psa. 11:7). He beholds and rewards those who seek peace and pursue righteousness (Matt. 6:33). The righteous remain steadfast when foundations are shaken because we have a kingdom that cannot be shaken. God is a consuming fire upon evil and the sustaining hope of all who serve Him “acceptably with reverence and godly fear” (Heb. 12:27-29). These are the things the righteous can do.
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).
Behold, I am coming quickly! Hold fast what you have, that no one may take your crown. (Revelation 3:11, NKJV)
The Christians in Philadelphia are highly commended by the Lord (Revelation 3:7-13). He had confidence they would use the opportunity He had opened for them to persevere and to prevail in their faith despite faithless opponents (Revelation 3:8-10). Christ would come with quick and complete justice upon their enemies. For their part, they were to “hold fast” what they had “firm unto the end” (see Hebrews 3:6). Their steadfastness was necessary in order that “no one may take your crown.” Jesus is crystal clear here. If they did not hold fast it would be possible for someone to take their crown (to prevent their victory). The doctrine of the impossibility of apostasy is absolutely obliterated by this passage. Why hold fast your faith if no one can take your crown? Why anticipate the coming judgment of the Lord against evil as an incentive to remain steadfast in the face of enemies of the faith? The truth is, if Christians abandon holding fast their faith, then they are not victors. They are among those who fall from grace (Galatians 5:4; Hebrews 6:4-6). Let us hold fast to the strength of faith, keep Christ’s word and not deny His name (Revelation 3:8). This is the victory of faith in Christ (1 John 5:4). Be warned. There is no victory in unfaithfulness.
