Colossians 2:22. "Which all are to perish with the using;) after the commandments and doctrines of men?"
COMMANDMENTS AND DOCTRINES. There are ways I can determine if a command is of men or of God. Often differences of opinions each claim to be based on God's Word. So, I will have to apply some test to see which things are right. I will have to reject the wrong, and be committed to walk in the light.
If man-made rules and taboos are the emphasis rather than grace - Right away I am sure this is a works-religion, definitely not one of faith. If it promotes a critical spirit and against others is always making complaint - That is contrary to discreet discipline and love that uses spiritual restraint.
Sometimes some people make claims of visions or knowledge known only to them. And insist they have some special formula not known by any other men. That is contrary to the Word of God, for the Bible is an open book. God's intentions are revealed in it if people only would take the time to look.
Any commandment or teaching that elevates self, rather than exalting Christ - Even though it may be taught by someone who is ever so kind and nice - Is wrong, and of that there is no doubt, God still resists the proud; And gives grace to the humble, that evidence of God's grace may abound.
Claiming to be the only ones who do right, and everyone else is wrong, Is evidence that a commandment or doctrine doesn't believe what God has done all along. There are believers all over the world God has been using for many generations To declare the Gospel of the grace of God, and He uses them to teach the way of salvation.
Asceticism is another false teaching that often appeals to those who are sincere. They try to humiliate themselves or go someplace where no one is near. Others turn their back on their families thinking this is what God demands. All these commandments and doctrines are only impositions placed on others by man.
"Father in heaven, preserve us from those who would side-track Thy people into a legalistic system made by men, or a careless system that appeals to the flesh. Keep us in Thy Word and faithful to Thee. In the name of the Lord Jesus Christ, Amen."
