Pure or Contaminated

DEVOTION
TITUS
PURE OR CONTAMINATED
Titus 1:14-16
15 To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. 16 They claim to know God, but by their actions they deny him. They are detestable, disobedient and unfit for doing anything good.
NIV
It would seem a person is either in or out, a true believer or not one at all. What is the difference between pure and corrupted? I think it is pretty clear that I am either clean or I am contaminated. The only thing which would contaminate or corrupt me would be the thinking of the world. If I accept the ideas, philosophy’s, and lifestyle of the world I surely would be contaminated from the pure faith and belief in my Lord. All the ways of the world, not just the illegal or immoral actions most believers think is bad, but all the ways of the world corrupt. Even the planning for retirement, the storing up of money, the investing it into companies which work against the Gospel for the sake of lining pockets with Gold is a corrupt concept of the world, not of God. If man’s heart is deceitfully wicked, always bend on self-pleasure of some form, how could I be a pure believer, if I adopted any of their thinking? How could I love both God and money? How could I love both God and this world? Sure I need things like all people do, but instead of serving the ways of the world and endeavor to attain those things myself, I need only to be pure and trust me God and he will provide all I need and more. I certainly do not what to be known as someone who only claims to know God, but lives just like all the other people who do not believe. Sure, I still fall in some areas of life. I do still have temptations which overcome me at times and I am not convinced that is being corrupt or contaminated, but merely being human, not divine. God knows my mind and my conscience. He knows how I am and my desires to be pure and acceptable in his sight. Of course the only reason I am is because of Christ. But I also have to live in accordance with his plan and purpose. If I am tainted by the ways of the world, what good am I to him? How can I preach or teach or write about his truth, if I live in accordance with the ways of the world? If I trust in filthy lucre instead of him, I am useless and unfit for any good in his kingdom. I must be pure.
