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.
