Gospel preachers need to be patient. They caused Moses trouble and they still cause God's leaders trouble. Evangelists need to possess the characteristic of continuance. They must not grow weary of teaching the same things over and over, but follow the example of Peter and Paul. As the qualifications of an evangelist are considered, it will be noted that it is a longer list than for either elder or deacon.
Nothing is stated about domestic qualifications.
In some ways being unmarried enables him to travel about more freely, but a good wife can also be an asset. No hint of age requirements are given, in fact we know Timothy was a young man. If a young man travels with an older evangelist, as did Timothy, he will experience in a short time enough troubles and problems which will help him cope with almost any difficulty that might arise in the average congregation. Men who can meet these requirements should be encouraged by elders, evangelists, and individual Christians to enter full-time service for the Master.
