"If my neighbour is not a Believer, and he runs into financial trouble, then he will apply certain worldy solutions in order to get out of this trouble. He is an atheist, and so looks to man to solve his problems.
If I (being a Believer) run unto financial trouble, and I do the same thing as my neighbour, then I am committing Practical Atheism. As a Believer, my heart should be dwelling on the affairs of God, so in any trouble, I must turn to him first. He may direct me to the same principals that my neighbour is following, but there is a fundamental difference: My neighbour turned to man to give him an answer to his problems, and I turned to God to give me an answer to my problems.
But He turned and said to Peter, "Get behind Me, Satan! You are an offense to Me, for you are not mindful of the things of God, but the things of men." - Matthew 16:23
There is a direct correlation between Satan, and our mind being on the things of men. If we consult knowledge and men before we consult God, in any part of our life, then we are saying by our actions that God is not real to us, and thus committing Practical Atheism."
- Bill Johnson, paraphrased by Jonathan Puddle.
