There are some things we do not need too.
But what if all these things were taken away from you. Could you cope and would you loose hope.
Would it make you think about the meaning of life?
I believe God is all we need. If we lost everything, God is still there. And God is tending to our every need.
Maybe make a plan. Give something negative up that is controlling you, and when you crave for that thing, think and talk with God about your struggle. Tell God that you he needs to increase and the other thing would decrease.
