Obvious Spiritual Strength

The word, 'prosperity' today nearly always refers to material wealth… but in context, we see that it is this dear man's physical health and bodily condition that John is praying will prosper. John's prayer is that Gaius' physical health will reflect his obvious spiritual strength and Christian maturity.
This verse clearly contradicts the distorted teaching of certain 'prosperity teachers' and 'faith-healers' who insist that if sick people do not recover, it is due to a lack of faith, or that if you are materially poor, you are not a spiritual believer because God wants all Christians to be materially wealthy! Such teaching is false and biblically incorrect.
The world 'soul' and 'life' are used interchangeably in the Word of God, and we discover that this man's spiritual life was fruitful – his soul was flourishing. He was working the works of God in his life through the power of the Holy Spirit.
Dear friend, I pray that you may enjoy good health and that all may go well with you, even as your soul is getting along well.

Our United Prayer:
Heavenly Father, thank You for the exemplary life of Gaius and this precious blessing written to Him. Thank You that You call us beloved and for all the blessings You pour into our lives. We pray that our souls would prosper with the riches of knowing You. We pray that, day by day, we would come to a deeper knowledge of the Lord Jesus as He increases in our lives. This we ask in Jesus' name, AMEN.
