He is not greater in this house than I am, nor has he kept back anything from me except you, because you are his wife. How then can I do this great wickedness and sin against God?” 
(Genesis 39:9)

Oh, if you and I always felt that God was near, looking steadily upon us, we should dare not sin. The presence of a superior often checks a man from doing what else he might have ventured on.

And the presence of God, if it were realized, would be a perpetual barrier against temptation and would keep us steadfast in holiness. This Jesus did perfectly for the Christian.

When Joseph afterwards at any time spoke of God, when God helped him not only to stand against temptation, but to do any service, you will notice how he always ascribed it to God.

He would not interpret Pharoah’s dream without first telling him, “It is not in me: God hath showed Pharaoh what he is about to do.” He was as conscious of the presence of God when he stood before the great monarch as when he refused that sinful woman.

I am afraid that we do not habitually talk in this fashion, but Joseph did. Without the slightest affectation he spoke out of his heart, under a sense of the divine presence and working.

How like he is in this to our divine Lord! The presence of God was everything to Christ as it was to Joseph. Now, if you and I set the Lord always before us, if our soul dwells in God, depend upon it—God is with us.

There is no mistake about it. ((Charles SpurgeonAt the Master’s Feet [Grand Rapids: Zondervan, 2005], December 3.))
