Charles Spurgeon Commentary Acts 8:27

"And he arose and went: and behold, a man of Ethiopia, a eunuch of great authority under Candace, queen of the Ethiopians, who was over all her treasure, who had come to Jerusalem to worship;" — Acts 8:27 (ASV)

And he arose and went:

Always do as you are told by your Lord. The first qualification for a good servant of Jesus Christ is immediate obedience.

And he arose and went:

Not hesitating, but at once obeying. If the Lord should send you to the wilderness, be assured that he will send somebody else there for you to bless; go, therefore, without fear.
