3 John 1:2 - Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.

First of all, you have to settle it in your mind and in your heart that God wants you to prosper. In fact, this scripture states that above all things, God wants you to prosper (financially) and be in health. There, however, is one part that many people miss when reading this scripture. That is the fact that, you will only be able to prosper (financially) and experience health to the level that your soul prospers. In order to clarify this scripture you must understand what the soul is.
