2 Beloved, I pray that you may prosper in all things and be in health, just as your soul prospers. 3 For I rejoiced greatly when brethren came and testified of the truth that is in you, just as you walk in the truth. 4 I have no greater joy than to hear that my children walk in truth. (3 John 2–4, NKJV)
John prayed Gaius’ physical health would match his spiritual health. How did John know Gaius’ soul was progressing successfully? Faithful brethren had told John of his beloved Gaius’ spiritual fitness. They reported the truth was in Gaius and that he walked in the truth (v. 3). Therefore, John concluded his soul prospered because Gaius believed and lived by the truth. One is not spiritually healthy when he or she does not abide in the word (truth) of Christ (Jno. 8:31-32). So, using this biblical standard, can it be said that your soul prospers? Is the truth of God in you? Are you walking in the truth? If so, the answer is “yes.” If not, the answer is “no.” God’s truth brings spiritual prosperity when we receive it and walk in it. John’s joy was made full by hearing his children (in the gospel, 1 Cor. 4:15) walked in truth. Faithful discipleship cannot exist when the truth is not in us and our deeds are not in harmony with it. Apply John’s prayer to yourself. If your physical health matched your spiritual health, how healthy would you be? When you answer these questions, “Is the truth in you?” and, “Are you walking in the truth?,” you will have the Bible answer to the state of your spiritual health.
