What you may not see in this translation is John’s hope for Gaius is two-fold, both that he may prosper financially as well as physically, just as his soul prospers. To prosper is to be financially well-off, to be “successful” or be financially secure. Someone who prospers is doing well. It is similar to the Vulcan benediction, “live long and prosper.” It is good wishes on those we care about. But what John adds here is the prosperity of the soul your physical and financial prosperity ought to be tied to how well your soul is doing. To be rich and healthy yet miserable is what we call Depression in America. What would you give to be happy? What would you give to have peace?
So what John wishes upon his friend Gaius is not so unusual. As a leader in the early church, he notes that physical and financial prosperity are both dependent on your soul’s health. And keeping a soul healthy depends on its reliance on the Lord. As he says in vs. 3, “you are walking in the truth.”
Soul health demands truth-walking. A healthy soul takes regular strolls through the halls of God’s word, takes in the sights, meditates on them, and allows them to fill his soul. He then can take his insights with him wherever he goes. If you are not spending time with God, you aren’t working on your soul.
So like a good pastor, John reminds Gaius (who probably didn’t need the reminder so much as those who would read the letter after him) that a healthy soul is necessary for physical health and financial health. As Paul once wrote, “godliness with contentment is great gain.” A godly soul is content even with a little, and considers it wealth. Don’t imagine for a minute John is inventing a “get rich” scheme here. The point of this physical health and prosperity is not to get religion. Being obedient to religious rules isn’t the beginning of a healthy retirement. Being obedient to the Lord is.
Like Gaius, let us hold fast the confession of our faith unwavering. And allow God to bless us in health and wealth as He sees fit. Let us not serve the Lord to be wealthy. Let us serve Him to be well in our soul. Yes, there is a return for faithful service. It is this, “Well done, my good and faithful servant. Enter thou into the joy of thy Lord!”
God bless you today!
