"Does not the ear test words, as the palate tastes its food?" (Job 12:11)
A Common Problem in the Early Church
The enemy's most effective weapon is deception, while our most powerful weapon is Truth. The early churches struggled mightily against the deception filled attacks of the enemy. In the midst of many of these battles, we find the Apostle Paul. His calling was to take the Truth of the Gospel to the gentile nations and God used him powerfully. However, the churches that he established with the new converts in the various regions were vulnerable to the enemy's attacks. It takes time, diligent study, and solid teaching for a congregation of new believers to grow in knowledge. Hence we have Paul continuously following up with the churches he founded via personal visits and letters.
Paul was an ardent advocate of critical thinking. His constant references to the mind and the need to use it and renew it are evidence of the abundance of ignorance and the vulnerability that characterized the early church. This is the idea behind Paul's warning to the Christians at Colossae.
"Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ (Col. 2:8, KJV)."
