Genesis 39:10 - Avoid falling under the spell of passion.

And it came to pass, as she spake to Joseph day by day, that he hearkened not unto her, to lie by her, or to be with her.

she spake to Joseph day by day - Potiphar's wife's intense desire to have sex with Joseph was relentless. Not only did Joseph continually refuse her illicit sex offers, he also took care not to be with her. By avoiding her, she couldn't entice him with her smooth offers of how having sex with her would be harmless and something to be enjoyed (Proverbs 7:18). Don't believe the lie, sexual immorality is harmful and something not to be enjoyed.

Genesis 39:9 - For Righteousness Sake

There is none greater in this house than I; neither hath he kept back any thing from me but thee, because art his wife: how then can I do this great wickedness, and sin against God?

How then can I do this great wickedness, and sin against God? There is a marked resemblance between Joseph's reason for not sleeping with Potiphar's wife and that of King Abimelech's reason for not sleeping with Sarah, Abraham's wife (Genesis 20:6). In both cases, sin was avoided for the sake of righteousness, gained through divine awareness. Man's righteousness is not only the result of human motives, for we also suffer for the sake of doing what is right.

Genesis 39:6 - A Good-looking Man

And he left all that he had in Joseph's hand; and he knew not ought he had, save the bread which he did eat. And Joseph was a goodly person, and well favoured.

There is a marked resemblance between Joseph's appearance and that of King David, they were both well-known for their striking handsomeness (1 Samuel 16:12 NIV).

Genesis 39:3 - Taking the Righteous Path

And his master saw that the LORD was with him, and that the LORD made all that he did to prosper in his hand.

His master saw that the LORD was with him because God's blessings crown the head of the righteous for all to see ( Proverbs 10:6). The LORD made all that he did to prosper because the righteous succeed in everything they do (Psalm 1:3). Like Joseph, take the righteous path, shining your light for all to see in everything you do.
