3 John 1:2 : Health

Beloved, I pray that all may go well with you and that you may be in good health, as it goes well with your soul. - 3 John 1:2 (ESV)

"Wishes for good health were standard in the openings of ancient Greek letters, but John prays for Gaius's health and also expresses care for his soul. Though spiritual growth can come through sickness and affliction (cf. Ps. 119:67, 71), it is right to pray for good health, as Jesus' earthly healing ministry also demonstrated."
