What does the Bible say about prospering in health?

In 3 John 1:2, the Apostle John expresses his heartfelt wish for Gaius to prosper in health, aligning it with the prosperity of his soul. This reflects a broader principle in Scripture that while physical health is valuable, it should be considered in light of spiritual well-being. The phrase 'even as thy soul prospers' indicates that true prosperity involves a flourishing relationship with God. The emphasis lies on the sovereignty of God in granting health or illness, reminding believers to seek His will in all matters.
