The enemies of God and of His people have always sought to conquer those weak in the faith by destroying their faith. Even now, false teachers seek to deceive the hearts of the simple – those who lack knowledge, understanding, and wisdom (Proverbs 8:5; Proverbs 9:4, 13). According to the scripture, these teachers do so “by good words and fair speeches.” It is not some raving, ranting lunatic that is most dangerous; it is the sweet talking, kind, loving, liar. In order to gain a following, a teacher must only appeal to others by sounding intelligent and offering “fair speeches” sprinkled with truth. If he can present things new to his audience, whether factual or not, the simple will become enamoured with his abilities and follow his teachings. This is why the Bible warns believers to have no fellowship with those who teach things contrary to the scripture. Any world religious leader who speaks softly and kindly yet fails to proclaim the true gospel probably lives more like a devil in private. The Bible calls these people wolves in sheep’s clothing.
When one side defeats another in battle, to the victor goes the spoils. This means that the victor enters the camp of the defeated and takes its valuable possessions (including women, children, material goods, etc.). With this truth in mind, the apostle Paul warned the believers at Colosse to be on guard, knowing that men would seek to spoil them through philosophy and vain deceit. In other words, accepting the philosophies of men, or false doctrines, is likened to losing a battle and allowing the enemy to rob the believer of his most valuable possessions. It is important to understand that although a believer can never lose his salvation, he can be robbed of his stability, growth, peace, and joy.
The Bible admonishes believers to be stedfast and unmoveable (1 Corinthians 15:58). We are to be grounded and settled (Colossians 1:23) in the faith—much like a tree planted by the rivers of waters (Psalm 1:3). Yet, today's passage points to the dangers of a hardened heart set in rebellion. It is likened to a stone and a millstone. We should remain stedfast in our commitment to serve the Lord, yet our hearts should remain tender and pliable to Him and His will. A stony heart hinders the seed of God’s word from taking root (Matthew 13:5-6). This hardness hinders the possibility of spiritual fruit from taking root and maturing. A soft heart and a stedfast walk exhibit the godly balance that God desires for each of us.
