Both God and Satan fight for our soul. God allows various temptations to happen to test us. Here's the danger. Something happens to you that gives you great pleasure. You know that continuing pursuing it would be wrong, but you are so amazed it happened to you that your think perhaps God intends it for you. You are right, but his intention is to test you. Now you are at a crucial point. The weak of faith fail and turn their back on God – I've seen that happen in the churches I belong or once belonged to. The strong in faith eventually pull through, with bruises and all, but also a faith now stronger than ever. In general, if you experience great turmoil and unrest within you, Satan is churning you up. God will always wish you to have his peace.
