God also works in our lives through meeting with non-believers.

Not only God makes us to be found favor in a non-believer’s sight (Gen. 39:4),

He also allows us to go through an unfair thing through the same non-believer (vv. 19-20).

But in the midst of going through the unfair thing, God makes us to meet another non-believer (40:1)

and get help from that non-believer (41:9-13).

And then, God makes us to meet another non-believer and exalts us (vv. 37-45).

Therefore, we must not think that we should always live only among the believers.

We only need to live in the Lord.  

God will cause all things to work together for good to us (Rom. 8:28) and

fulfills His good, pleasing and perfect will (12:2)

through all the meetings the Lord allows in our lives.
