1 Corinthians 3:18-19
18 Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.
19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
The world is a foolish place. It will deceive you to believe that you are fine with God. The world will convince you that a little sin is okay. The world can even convince you that you are wise in the word of God. The truth is, if you are getting your information about salvation from the sinful world, then you are sadly misled. The thing is, the adversary wants you to be foolish and believe that you are wise. You become arrogant and tell others that you know what you are doing and in the end you where wrong. Stop listening to the enemy and the lies that the enemy says. If you want to be wise and know that you are in the will of God, do not listen to the foolishness of this world. Instead, study the word of God and pray for the spirit of the lord to guide you.
