These things I have written to you concerning those who try to deceive you (1 John 2:26, NKJV).
The possibility of being deceived about spiritual matters is just as real today as when the apostle John wrote to the children of God. As then, many are still against Christ yet pose as if they are for Christ; Hence, the warning against being deceived (1 John 2:18-19). John emphatically directs us, “Do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world” (1 John 4:1). How? By using the truth with which Christ has endowed (anointed) us: “But you have an anointing from the Holy One, and you know all things. I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth” (1 John 2:20-21). The truth Jesus Christ gave us through His apostles (1) Identifies the deceptions of false teachings (1 John 4:6), and (2) Assures our fellowship with the Father and the Son (John 14:21-24), and (3) Leads us to His promise of eternal life (1 Pet. 1:3-9). John says these are among the reasons we let His word abide in us (1 John 2:24-27; John 8:31-32). Use God’s word to verify your faith. Rejoice in your fellowship with God and be comforted in Christ’s promise of eternal life. Rest assured, God’s word of truth will not deceive you.
7 Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap. 8 For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life. (Galatians 6:7–8, NKJV)
Jeremiah said the human heart is deceitful (Jer. 17:5). Indeed. Since our hearts can deceive us, Paul’s warning is for us all. God is not mocked; we do not deceive God. We will reap what we sow. Like Israel (who sowed the wind and reaped the whirlwind, Hos. 8:7), we will reap the results of the life we choose. With this sober reminder, Paul begins to conclude his exhortation to walk in the Spirit and not the flesh (Gal. 5:16-6:10). Fulfilling the lust of the flesh produces the works of the flesh and results in eternal corruption (Gal. 5:16, 19-21; 6:8). But, walking in the Spirit bears the fruit of the Spirit that results in everlasting life (Gal. 5:16, 18, 22-25). Helping one overtaken by sin is sowing to the Spirit (Gal. 6:1-2). Envious conceit and self-promotion sow to the flesh (Gal. 5:26; 6:3). Sharing in all good things with our teachers is sowing to the Spirit, but refusing to do so is a trait of the flesh (Gal. 5:20; 6:6). Paul’s broader context bears out this principle. Those who tried to be justified by the law failed and forfeited being led by the Spirit (Gal. 5:3-4, 18). We are accountable to God for what we sow in life (2 Cor. 5:10). When judgment comes, will we reap sorrowful tears or joyful glory? Do not be deceived.
9 Do not lie to one another, since you have put off the old man with his deeds, 10 and have put on the new man who is renewed in knowledge according to the image of Him who created him” (Colossians 3:9-10)
A lie is a falsehood, an untruth, a deception. Every day we face many temptations to lie, from fudging our taxes to calling into work “sick” when that is not at all the case. Christians deliberately choose not to be deceptive – even if it costs them. And, it will. But, Christians choose to follow the example of Christ – and there was never deceit in His mouth (1 Pet. 2:21-22). Make up your mind that you will be a person of truth, honesty and integrity every day. By doing so you will “put off the old man with his deeds” and “put on the new man” who is conformed to the image of Christ. Be like Christ – not like sinners.
