Well, you don't have to. We are here on this physical plane for a purpose.
I believe as a test. A test how we truly treat each other. We are here as an extension of God...and continuation of that life force within us. There are moments where we could be superheroes, supervillians, a participant, or a pawn in this life to somebody. We have to understand why we do the things we do in order to understand others. Then we evolve. We have to understand that evolution before we evolve to the next. Human beings and spirits are capable of some great things and horrendous things. Understanding is a part of knowing truth...and there are many truths in people.
If God works in mysterious ways...and we are created in His image...don't you think we are mysterious...yet capable of understanding? I believe we are an extension of God's life force. A testimony of great things--constructive and destructive. We are supposed to evolve. Learn and understand why we evolved and move on to the next evolution and understand that.
I love this it's really deep. I think it sums it all up.
