Col. 2:16-17 "So (or therefore) let no one judge you in food or in drink, or regarding a [j]festival or a new moon or sabbaths, 17 which are a shadow of things to come, but the [k]substance is of Christ, In other words, we are free from the legalistic applications of the law. Looking back at Verses 9-10 "For in Him dwells all the fullness of the Godhead [f]bodily; and you are complete in Him, who is the head of all [g]principality and power."

We are complete in Him. The legal restrictions that were in place through the Mosaic Law no longer are required, because Jesus fulfilled the law, and he fulfills us or completes us as well. There is nothing more we need to do for our salvation. Believe in Him and you will be saved’
