A. Greeting and introduction.
1. (1) The writer and the reader.
The Elder, To the beloved Gaius, whom I love in truth.
a. The Elder: The writer of this book identifies himself simply as the Elder. Presumably, the first readers knew who this was, and from the earliest times, Christians have understood that this was the Apostle John writing, the same John who wrote the Gospel of John, 1 and 2 John, and the Book of Revelation.
i. Perhaps he does not directly refer to himself for the same reason he does not directly refer to his readers in 2 John – the threat of persecution may be making direct reference unwise; and of course, unnecessary.
b. To the beloved Gaius: We don’t know if this specific Gaius is connected with the other men by this name mentioned in the New Testament (Acts 19:29, 20:4; 1 Corinthians 1:14; Romans 16:23).
i. The identification is difficult because Gaius was a very common name in the Roman Empire.
2. (2-4) A blessing for faithful Gaius.
Beloved, I pray that you may prosper in all things and be in health, just as your soul prospers. For I rejoiced greatly when brethren came and testified of the truth that is in you, just as you walk in the truth. I have no greater joy than to hear that my children walk in truth.
a. Beloved, I pray that you may prosper in all things: The word for prosper literally means “to have a good journey.” It metaphorically means to succeed or prosper. It is like saying, “I hope things go well for you.”
i. “Both verbs [for prosper and be in health] belonged to the everyday language of letter writing” (Stott). This phrase was so common that sometimes it was condensed into only initials, and everyone knew what the writer meant just from the initials.
ii. The abbreviation used in Latin was SVBEEV, meaning Si vales, bene est; ego valeo – “If you are well, it is good; I am well.”
b. I pray that you may prosper in all things and be in health, just as your soul prospers: John used this common phrase in sending his best wishes and blessings to Gaius. Some have wrongly taken this as a guarantee of perpetual wealth and perfect health for the Christian.
i. Of course, we should always remember that God wants our best and plans only good for us. Often present material prosperity and physical health are part of that good He has for us – and this prosperity and health are absolutely promised as the ultimate destiny of all believers.
ii. Yet, for the present time, God may – according to His all-wise plan – use a lack of material prosperity and physical health to promote greater prosperity and health in the scale of eternity.
iii. Nevertheless, some live in poverty and disease simply because they do not seek God’s best, follow God’s principles, and walk in faith. As well, there are some others who say we should use God’s general promises of blessing as a way to indulge a carnal desire for ease, comfort, and luxury.
c. Just as your soul prospers: John here made an analogy between the condition of our health and the condition of our soul. Many Christians would be desperately ill if their physical health was instantly in the same state as their spiritual health.
d. I have no greater joy than to hear that my children walk in truth: John’s goodwill towards Gaius came from his understanding that he walked in the truth. Nothing pleased John more than to know that his children walk in truth.
i. John knew that Gaius walked in truth because brethren came and testified of the truth that was in Gaius. His walk of truth was noticed by others, and they could talk about it because they saw it.
e. That my children walk in truth: This means more than living with correct doctrine. “What is it to ‘walk in truth’? It is not walking in the truth, or else some would suppose it meant that John was overjoyed because they were sound in doctrine, and cared little for anything else. His joyous survey did include their orthodoxy in creed, but it reached far beyond.” (Spurgeon)
i. To walk in truth means to walk consistent with the truth you believe. If you believe that you are fallen, then walk wary of your fallenness. If you believe you are a child of God, then walk like a child of heaven. If you believe you are forgiven, then walk like a forgiven person.
ii. To walk in truth means to walk in a way that is real and genuine, without any phoniness or concealment.
B. Learning from good and bad examples.
1. (5-8) Gaius: A good example.
Beloved, you do faithfully whatever you do for the brethren and for strangers, who have borne witness of your love before the church. If you send them forward on their journey in a manner worthy of God, you will do well, because they went forth for His name’ssake, taking nothing from the Gentiles. We therefore ought to receive such, that we may become fellow workers for the truth.
a. You do faithfully whatever you do for the brethren and for strangers: John praised Gaius for his hospitality. This may seem somewhat trivial to us, but it is not to God. This is a practical outworking of the essential command to love one another; it is love in action.
i. This was a great compliment: you do faithfully whatever you do. Whatever God gives us to do, we should do it faithfully. Jesus said that when we see Him face to face some will hear the words, well done, good and faithful servant; you were faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord (Matthew 25:21). Of the good servant, it is said he was faithful.
b. Send them forward on their journey in a manner worthy of God: In that day, Christian travelers in general and itinerant ministers in particular were greatly dependent upon the hospitality of other Christians. John knew that when Christians assist those who contend for the truth, they become fellow workers for the truth.
i. The reward for these support people is the same as those who are out on the front lines. 1 Samuel 30:21-25 shows this principle, where the spoils are distributed equally among those who fought and those who supported. King David understood that the supply lines were just as vital as the soldiers, and God would reward both soldiers and supporters properly and generously.
ii. Jesus promised that even the help offered in a cup of cold water to one of His children would not be forgotten when God brings His reward (Matthew 10:42).
iii. This also explains why John would pray for the prosperity of Gaius: he used his resources in a godly way, being a blessing to others. If God blessed him with more, others would be blessed more also.
c. Taking nothing from the Gentiles: The ancient world of the early church was filled with the missionaries and preachers of various religions, and they often supported themselves by taking offerings from the general public. But John said that these Christian missionaries should take nothing from the Gentiles (non-Christians). Instead of soliciting funds from the general public they were to look to the support of fellow Christians.
d. In a manner worthy of God: Christians are not only called to help, but to help in a manner worthy of God. We are to do our best to help others excellently.
i. Christians must first see that they are doing something to help the spread of the gospel. Then they must see that they do it in a manner worthy of God. God calls everyone of us to have a part in the great commission, the command of Matthew 28:19: Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit. One can have a part by going or have a part by helping, but everyone has a part and should do it well.
ii. Jesus said, He who receives you receives Me, and he who receives Me receives Him who sent Me. He who receives a prophet in the name of a prophet shall receive a prophet’s reward. And he who receives a righteous man in the name of a righteous man shall receive a righteous man’s reward (Matthew 10:40-41). This should make us consider how we receive and help those who preach the Gospel.
