Philippians 2:25-30:

Yet I supposed it necessary to send to you Epaphroditus, my brother, and companion in labour, and fellowsoldier, but your messenger, and he that ministered to my wants.
For he longed after you all, and was full of heaviness, because that ye had heard that he had been sick.
For indeed he was sick nigh unto death: but God had mercy on him; and not on him only, but on me also, lest I should have sorrow upon sorrow.
I sent him therefore the more carefully, that, when ye see him again, ye may rejoice, and that I may be the less sorrowful.
Receive him therefore in the Lord with all gladness; and hold such in reputation:
Because for the work of Christ he was nigh unto death, not regarding his life, to supply your lack of service toward me.

Notes on Philippians 2:25-30:

Being involved in any form of Christian ministry does not exempt you from the need to take reasonable care of your body.  Many ministers make the mistake that Epaphroditus did and push their bodies beyond what is reasonable.  I’ve known a couple ministers who almost died as a result, but God had mercy on them as He did on Epaphroditus.

I’ve heard ministers say, “I’d rather burn out for Jesus than burn out for the world.”  I say, and I would encourage you to say, “I don’t want to burn out at all!  I’d rather take care of my body and exercise wisdom.”
