What does the Bible say about prosperity of the soul?

In 3 John 1-4, the Apostle John expresses his desire for Gaius to prosper in all things, but notably ties this desire to the prosperity of Gaius' soul. This highlights the biblical principle that material prosperity should align with spiritual prosperity. The health and success John desires for Gaius are rooted in a vibrant spiritual life that reflects God’s grace and provision. A soul that is nourished in Christ and aligned with God's will will naturally manifest in the believer’s daily life, leading to genuine prosperity in physical and social realms as well.
