SUITABILITY. Titus 3:13 God has gifted each of us in ways best suited for us to do the work He gives us. Sometimes, one of the Lord's servants can help others financially and encourage them in their work. Building someone up has much more lasting value than being critical and tearing down a fellow believer's credibility.
Every servant of the Lord is unique, whether recognized mainly by their occupation, like Zenas the lawyer, or by their preaching ability, like Apollos the eloquent speaker. The reason they happened to be in Crete at that time isn’t explained. Perhaps they had delivered Paul’s letter to Titus and stayed on for some meetings in the churches there. Zenas was probably an expert in the law of Moses, although he could also have been knowledgeable in Roman law. Apollos was a well-known and talented preacher who could speak passionately about a message.
A lawyer could have impressed the Cretans with his knowledge of the law, unlike the false teachers trying to gain followers there. He would have been able to address their argumentative opinions and support Titus's teaching. Apollos could have held an audience and overcome their petty squabbles with his passion, eloquence, and spiritual understanding learned from others like Aquila and Priscilla.
It was a practice then and should be today to show hospitality of any kind to those who preach the Gospel and minister the word of God to the Lord’s people. In the apostle John’s letter to Gaius, he commended him for showing hospitality to the brethren who were traveling through as they went about their work for the Lord. They didn’t take support from those who were unbelievers, but by believers supporting those engaged in the commission our Lord gave, they became “fellow workers for the truth.”
