Hmmm... idk... Your mistake... not sure what that means. I keep thinking about Abraham, how he and Sarah decided to try to use their own way to make a son, and then hope that God would bestow the promise upon him. He was their mistake and God still had a son of promise by whom he would do all that he had said. God's not obligated to bless the mess we make trying to help him out-- the gifts that he gave us were given with his purpose in mind, so it is those gifts that will bring you into what he has already designed for you.
I was praying last week, and God was showing me that if we stay in him and obey him even when the future doesn't look clear or even promising, he will bring us to where we need to be. His plan will be fulfilled in our lives, then we don't have to worry so much, just focus on him and seeking him with all our hearts and obeying what he gives us to do.
