What are you clinging too?
Are you clinging to rules to keep your way pure?
Are you clinging to fear?
Are you clinging to control?
Are you clinging to pride?
We can cling to all of those things in the mask of being "pure".
But we should be clinging to the cross. Looking to the self-sacrificing work of Jesus on the cross.
Anytime we try to put man-made rules on being "righteous" we will fail!
We're warned about this in Colossians 2:20-23
20 If with Christ you died to the elemental spirits of the world, why, as if you were still alive in the world, do you submit to regulations— 21 “Do not handle, Do not taste, Do not touch” 22 ( referring to things that all perish as they are used)—according to human precepts and teachings? 23 These have indeed an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but they areof no value in stopping the indulgence of the flesh.
If you have no heart for purity and are "following" the rules, although they may appear wise, they will not address the idols of your heart!
Get the heart of purity. Where Christ is!
