(Col 2:6) As ye have therefore received Christ Jesus the Lord, so walk ye in him:
(Col 2:7) Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.
(Col 2:8) 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 2:9) For in him dwelleth all the fulness of the Godhead bodily.
(Col 2:10) And ye are complete in him, which is the head of all principality and power:
How did you receive Christ by faith or by works? By faith of course. How is it that a man may spoil you through philosophy and vain deceit? By setting standards that draw you into a hope in yourself and not in Christ.
What does it mean to be complete? Nothing more needed. The Artist has signed His work and it is finished. He will not strike the hammer to His chisel again in order to finish the sculpture.
(Col 2:16) Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
(Col 2:17) Which are a shadow of things to come; but the body is of Christ.
(Col 2:18) Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,
(Col 2:19) And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.
(Col 2:20) Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances,
(Col 2:21) (Touch not; taste not; handle not;
(Col 2:22) Which all are to perish with the using after the commandments and doctrines of men?
(Col 2:23) Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh.
Read this passage over several times. Religious rigidity is a show of wisdom in will worship. It does nothing but satisfy the flesh.
Oh how good I feel when I act like I am holy in myself. It is a false spirituality and a show.
Trust that Christ is enough for the Father and enough for you and go and live in this world as believers whose only hope is the Lord Jesus Christ. You will not need to be driven to a godly life it will come naturally.
Rolf Barnhard made this statement once: We have got far too many saved people today, What we need is to get some people lost. [Not a direct quote]
If you want to tell the difference between religion and true faith here it a plumbline to judge by: religion is always about things, such as is this thing or that thing sin, am I living right, how much should I give, should I watch TV or movies and all sorts of things. True faith is about a Person, the Lord Jesus Christ and faith in Him.
