You are in the middle of fulfilling purpose. Do not turn back or make a mistake because you only have the bits and pieces. Do all that you can to work with the bits and pieces. Abraham only knew one little bit, which was that God was calling him to go to a place where He would bless Him. Abraham was going to father a nation, but God did not give him all of the details (v8).
You might be in the middle of being a blessing to your entire generation, but you do not know how at this stage. To work with the bits and pieces that we already have, we need to accept the fact that we will never know all. God will only reveal what we need to know and only when we need to know it.
The only bits and pieces that Joseph had were that he had dreamed two dreams; and his father interpreted it as being that he (Jacob) and Joseph’s brothers would bow to him. That is all that Joseph knew. David did not know much more either. All he knew was that he was anointed to be king. How and when was not known to David. But he worked with God. He worked with the bits and pieces that he knew and went through periods of exile and running for his life.
Homework: Ask God to help you use the bits and pieces of information that He has already given you to help you work towards your destiny and purpose.
