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 truly incredible how so many people insist on propping up the false doctrine that Christians cannot fall away from the Lord and be lost. The false doctrine suggests teaching the possibility of apostasy diminishes God’s power to save. That is a diversionary, deceptive, and destructive lie of the devil, the father of lies. Of course, God has the power to save. Human free will is also a part of the equation; We are saved “by grace” (God’s part) “through faith” (our part) (Eph. 2:8). Without free will, we are mere robots. God becomes an unjust tyrant, selecting some for salvation and others for damnation regardless of their conduct. That cannot be true (Acts 10:34-35; 17:30; Rom. 2:1-11; 3:4). Today’s passage overwhelms the false doctrine of once saved, always saved. Some had already fallen. Peter warns beloved Christians, “lest you also fall from your own steadfastness, being led away with the error of the wicked” (v. 17). The countermeasure to prevent falling is spiritual growth in the “grace and knowledge of our Lord and Savior Jesus Christ” (v. 18). When we mature in understanding and apply our faith to follow the Lord, Jesus is honored “both now and forever,” not ourselves. We dare not minimize (or even rejecting) the truth that Christians can fall and be lost. Instead, remain steadfast in your faith by growing in the grace and knowledge of the Lord.
9 Does he thank that servant because he did the things that were commanded him? I think not. So likewise you, when you have done all those things which you are commanded, say, ‘We are unprofitable servants. We have done what was our duty to do.’ (Luke 17:9–10, NKJV)
Followers of Jesus want to grow in their faith to reach spiritual maturity. This growth of faith comes as we feed on the word of God and live by its truth (Heb. 5:12-14). By using the word of God we grow and are strong in Christ. Even so, in today’s passage, the Lord explains our faith will increase when we obey the duty of faith. Just as a servant obeys his master out of duty and without merit, our obedience to Christ expresses full submission to Him. We merit nothing by our obedience (we cannot earn our way to heaven) – we are “unprofitable servants” doing our duty (v. 10). Our faith in Christ compels our obedience to Him. It is our duty to obey His word, and we freely and willingly do so. Such submissive obedience shows we trust the Lord instead of ourselves. We do His will in His way precisely because we trust His way is right and good. That kind of faith grows as we fulfill our duty before the Lord. You see, saying and not doing is not faith (Lk. 6:46; Jas. 2:17). Doing our duty as servants increases our faith in the Lord.
7 And which of you, having a servant plowing or tending sheep, will say to him when he has come in from the field, ‘Come at once and sit down to eat’? 8 But will he not rather say to him, ‘Prepare something for my supper, and gird yourself and serve me till I have eaten and drunk, and afterward you will eat and drink’? (Luke 17:7–8, NKJV)
Jesus continues to explain how to increase our faith as He answers the apostles’ request to “increase our faith” (Lk. 17:5). We cannot fail but see that Jesus explains there are things we must do for our faith to grow. Faith is powerful when it is active (Lk. 17:6-7). Furthermore, faith grows when faith serves. We are servants of God and of one another, not masters. Our duty is to serve the will of God, not ourselves. Faith does not elevate us to a place where we demand the Lord serve us. He is the Teacher and Lord, who willing served the Father’s will for our salvation. Now, our faith compels us to be servants (Jno. 13:13-17). That includes the service of forgiving others and being careful not to become offenses (snares) to them (Lk. 17:1-4). Servants of Christ live by faith, doing His will from the heart. The servant heart is fertile ground that bears the fruit of the Spirit by holding fast to God’s word and living as a servant (Lk. 8:15; Gal. 5:22-26). Thus far, Christ has said our faith will increase when we 1) Trust the power of faith (Lk. 17:6), and when we 2) Offer the service of faith (Lk. 17:7-8). What He will say next adds a third item to this list of how to increase our faith.
14 that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting, 15 but, speaking the truth in love, may grow up in all things into Him who is the head—Christ— (Ephesians 4:14–15, NKJV)
Maturity in Christ equips us to achieve and maintain the “the unity of the faith” to which we have been called by the gospel. Christ gave the work of inspired men (through which that gospel came to earth from heaven), and the work of uninspired men (who continue to proclaim and teach the gospel) to thoroughly equip us to serve the will of God as the body of Christ (Ephesians 4:11-13). In today’s text, our spiritual maturity prevents us from being tossed about like children by the prevailing winds of false doctrine. The “trickery of men” describes the sleight of hand by which one defrauds another. False doctrine defrauds and plunders the unsuspecting of their spiritual treasure (Colossians 2:8). The “cunning craftiness of deceitful plotting” describes the deceptive method of sophistry that attacks the simplicity of the gospel of Christ (Romans 16:17-18). As our maturity in Christ protects us, it also enables us to speak the truth in love. God’s truth equips us to grow in Christ, while protecting us from spiritual danger, and securing our standing with Christ (the Head of the church). Let us determine to grow up in Christ by becoming strong in the truth.
But put on the Lord Jesus Christ, and make no provision for the flesh, to fulfill its lusts. (Romans 13:14, NKJV)
Having already told Christians to wake up and clean up, the apostle now tells us to grow up (Rom. 13:11-13). While it is true we put on Christ when we “first believed” (when we were baptized into Christ, Gal. 3:27), we must continue to clothe ourselves with the Lord. Successful godly living requires spiritual growth in order to make decisions that glorify God and avoid sin. If we fail to grow up in Christ it will become easier to provide for sin. Do not plan to sin. Guard your heart against lustful thinking and cast off the darkness that gives occasion to fulfilling sinful desires. Starve the flesh of sinful lusts; put it to death. Be clothed with the Lord Jesus Christ. Be filled with and comforted by His righteous truth. He abundantly provides all things for life and godliness. Remember, salvation is nearer than when you first believed (Rom. 13:11).
