“…how then can I do this great wickedness, and sin against God?” Genesis 39:9

A man who is favour conscious, is conscious of God with him and as such, walks in righteousness. He knows his advancement in life isn’t determined by joining the ungodly but by the hand of God upon him and so it is no surprise that when Joseph had an opportunity to do wrong against his master by sleeping with his wife, courting her favour, he refused:
“…how then can I do this great wickedness, and sin against God?” Genesis 39:9
Remember, the law of Moses didn’t exist then, so what was his guide and deterrent? His consciousness of the presence of God. He had all the reasons to be ungodly- he was in a strange country after all, sold by his brothers, made a prisoner, where was God in all of this?
“…but God was with him,” Acts 7:9
Never let the circumstances you face cause you to act as though God isn’t with you and you begin to choose temporal satisfactions in exchange of a better and permanent elevation. He could have slept with Potiphar’s wife, the exchange? His family, Egypt (himself, Pharaoh, Potiphar and wife) would have died of hunger during the famine.
