When I first saw your question, I thought saturated as a spiritual term. A term for being fully immersed and enamored by the presence of Almighty God. He is an all consuming fire. He fills to overflowing. Saturated or filled to the point where you can't hold any more. Only God can make your life so abundant and full. However, you must want Him and cry out to Him.
For a more definition based idea, saturated is a term about the water or fluid content of a particular item. If you are talking about a sponge that is saturated, it can't hold any more liquid. It is filled completely. Every pore in that sponge is full with liquid.
