3 Some people may contradict our teaching, but these are the wholesome teachings of the Lord Jesus Christ. These teachings promote a godly life. 4 Anyone who teaches something different is arrogant and lacks understanding. Such a person has an unhealthy desire to quibble over the meaning of words. This stirs up arguments ending in jealousy, division, slander, and evil suspicions.
Matthew Henry's Commentary on 1 Timothy 6:3-4
Commentary on 1 Timothy 6:1-5
(Read 1 Timothy 6:1-5)
Christians were not to suppose that religious knowledge, or Christian privileges, gave them any right to despise heathen masters, or to disobey lawful commands, or to expose their faults to others. And such as enjoyed the privilege of living with believing masters, were not to withhold due respect and reverence, because they were equal in respect to religious privileges, but were to serve with double diligence and cheerfulness, because of their faith in Christ, and as partakers of his free salvation. We are not to consent to any words as wholesome, except the words of our Lord Jesus Christ; to these we must give unfeigned consent. Commonly those are most proud who know least; for they do not know themselves. Hence come envy, strife, railings, evil-surmisings, disputes that are all subtlety, and of no solidity, between men of corrupt and carnal minds, ignorant of the truth and its sanctifying power, and seeking their worldly advantage.
