Colossians 2: 16-19 (NLT) 16 So don’t let anyone condemn you for what you eat or drink, or for not celebrating certain holy days or new moon ceremonies or Sabbaths. 17 For these rules are only shadows of the reality yet to come. And Christ himself is that reality. 18 Don’t let anyone condemn you by insisting on pious self-denial or the worship of angels, saying they have had visions about these things. Their sinful minds have made them proud, 19 and they are not connected to Christ, the head of the body. For he holds the whole body together with its joints and ligaments, and it grows as God nourishes it.
Condemnation comes from satan and weighs us down with guilt for things that we have done in the past or things that we are doing now. If satan can keep you feeling guilty, he has defeated you because you will not be able to do good works when you are weighed down with guilt. Remember that there is no condemnation for those of us who are in Christ Jesus. Condemnation is different from conviction. God’s Holy Spirit will bring conviction upon us but it will lead us to repentance. Once we have repented, our relationship with Jesus is restored and we can again be effective working for Christ. Man should not add any requirements for salvation to what God has already laid out in His Word. No matter what anyone tells you, we cannot live good enough to earn salvation or bad enough to lose our salvation. Our salvation depends on Jesus and His shed blood. God tells us in Romans that nothing, absolutely nothing, can separate us from Him and His love. Why? Because it is a gift from God and gifts cannot be bought or earned.
All the rules and precepts are shadows of what is coming. It is our responsibility to use discernment and cross check what people say with the Holy Scriptures. If the two do not agree, then we must always go with the Word. Just as our physical bodies are controlled by our brains (head) and nourished by the blood flowing through it , so is the Spiritual body controlled by the head, who is Christ Jesus. The whole body is held together by the power of His Word and is nourished by His Spirit flowing through us.
