Genesis 39:7-9 (NKJV)
And it came to pass after these things that his master’s wife cast longing eyes on Joseph, and she said, “Lie with me.” But he refused and said to his master’s wife, “Look, my master does not know what is with me in the house, and he has committed all that he has to my hand. There is no one greater in this house than I, nor has he kept back anything from me but you, because you are his wife. How then can I do this great wickedness, and sin against God?
You know the story of Joseph and Potiphar's wife. Potiphar had purchased Joseph as a slave and made him head of his household. But then Potiphar's wife took a liking to the handsome young Joseph and tried to seduce him. But notice Joseph's reply: he was not worrying about sinning against Potiphar—he was worried about sinning against God! David the Psalm writer would later say "against Thee and Thee only have I sinned" when repenting of his stealing Bathsheba and killing her husband Uriah. Yes, innocent people suffer when we sin but God is the one chiefly offended. This is the right kind of understanding we need to have about God and sin.
Genesis 39:19-23
So it was, when his master heard the words which his wife spoke to him, saying, “Your servant did to me after this manner,” that his anger was aroused. Then Joseph’s master took him and put him into the prison, a place where the king’s prisoners were confined. And he was there in the prison.
Any normal person would be totally discouraged but Joseph is a man of integrity. No matter what happens to him he continued to trust the Lord and to do his work as unto Him. I am sure Joseph still remembers the dreams of his brothers bowing down before him and he has to be wondering how God will work this out.
Genesis 39:21, 23
But the Lord was with Joseph and showed him mercy...and whatever he did, the Lord made it prosper.
God’s plan for the believer will include unexpected detours and unexpected blessings.
