Service was one of the main links in the remarkable chain of events that God brought about in Joseph's life. Now he was made responsible for the king's butler and baker, for "he served them" (Gen. 40:4).
Joseph was made responsible for them because his godly character had won him favor with those in authority. And Joseph was willing to serve in any way he could.
As Joseph faithfully served God by serving others, little did he know how God would use his association with the butler and baker to bring about His will. Because God was in it, the relationship of the Hebrew slave with Pharaoh's two servants had far-reaching results.
We also need to realize that the smallest circumstance of life has meaning.
Even though we may not understand how God can use a particular thing to work out His glory, we need to realize that He can use small things as well as big things to accomplish His will.
The words, "all things," are very important words in Romans 8:28: "And we know that all things work together for good to them that love God, to them who are the called according to his purpose."
Note particularly that Joseph's religious convictions did not stand in the way of earthly promotion. Men of the world soon detect when a person has quality of character. Joseph did not compromise to obtain promotions; the promotions came because he had a character that would not compromise.
"Only fear the LORD, and serve him in truth with all your heart; for consider how great things he hath done for you" (1 Sam. 12:24).
