Romans 15:32 "so that in God's will, I may come to you in joy and be refreshed by your company "
This is talking about Paul longing to visit other believers, desiring the joy and the wonderful time of refreshing with them. This is also exactly one of the reasons the Lord wants us to gather together. There is joy and encouragement in the house of the Lord. Let's get together on Sunday mornings and lots of other days too, for times of refreshing.
