Joseph is not destroyed even by this experience. He goes on showing Christian character.
We do so many things that are wrong, all of us. Sinful things, foolish things, and sometimes you are reproved, maybe by your wife, maybe by your husband, maybe by your teenage child, which comes as a shock to you. What an impertinence! But the boy or the girl may be right, and how are you going to take it? Sometimes from a friend, sometimes in our circumstances, the Lord overruling in some way. Sometimes we take it very badly. Sometimes people become very hard towards being capable of knowing conviction of sin or wrong, and that's a terrible thing for a Christian. If we find ourselves in that situation, that's a big warning. Of course, it could be that the person is not a believer, but it could be that we just become too proud or hardened our hearts, and we haven't been listening to the voice of conscience. If you ever think that is happening to you, go pray about it and take yourself in hand. Joseph didn't deserve reproof, and yet he still took it, and the Lord blessed him on account of it.
Bishop Hall says, ‘No prison would serve him but Pharaoh's. Joseph had lain obscure, and not been known to Pharaoh, if he had not been cast into Pharaoh's dungeon. The afflictions of God's children turn ever to their advantages. No sooner is Joseph a prisoner, than a guardian of the prisoners. Trust and honour accompany him wheresoever he is: in his father's house, in Potiphar's, in the jail, in the court still he hath both favour and rule.’
