Puzzled about How to Treat God's Servants?

1 Corinthians 16:10-12, 15-18

10 When Timothy comes, see to it that he has nothing to fear while he is with you, for he is carrying on the work of the Lord, just as I am.

11 No one, then, should treat him with contempt. Send him on his way in peace so that he may return to me. I am expecting him along with the brothers.

12 Now about our brother Apollos: I strongly urged him to go to you with the brothers. He was quite unwilling to go now, but he will go when he has the opportunity.

15 You know that the household of Stephanas were the first converts in Achaia, and they have devoted themselves to the service of the Lord’s people. I urge you, brothers and sisters,

16 to submit to such people and to everyone who joins in the work and labors at it.

17 I was glad when Stephanas, Fortunatus and Achaicus arrived, because they have supplied what was lacking from you.

18 For they refreshed my spirit and yours also. Such men deserve recognition.
