The Joseph Story continues with Gen 42:38 and Gen 43:13. Also see Dan 2:21. Jacob was holding on to Benjamin because he didn't want to lose him. But when there was no food left, he had no choice and had to let him go to Egypt. That act released the blessings of God and changed the world.
God can change what no man can change. When we have a problem that is too big for us, whether in our personal, business or national life. Jesus can heal it. He can solve the problem!
