Genesis 40:23 Yet did not the chief butler remember Joseph, but forgat him.
Joseph had helped the butler. The butler forgot Joseph and did not help him. I can only imagine how that made Joseph feel.
If you are in the ministry of serving people then you know that you have been forgotten. People have promised to remember. People have promised to help but they have forgotten.
Welcome to the club. Just do your job knowing that God will not forget!
