In Acts.18: 2-3, we find the Apostle Paul in Corinth. Its location controlled the trade routes between the Aegean and Adriatic seas. Greeks, Romans, and Middle Easterners met in Corinth to do their business. There he met Aquila and his wife Priscilla and stayed with them as he was of the same trade as they were. He found them eager to learn the true way and so he trained them. His life is a textbook for evangelists and ministers. In 2Tim.3: 10-11, we find Paul giving his testimony ,’You, however, know all about my teaching, my way of life, my purpose, faith, patience, love, endurance, persecutions, suffer­ings-what kinds of things happened to me in Antioch, Iconium and Lystra, the persecutions I endured. Yet the Lord rescued me from all of them.’ 

 I. PAUL’S TRAINING SYLLABUS:  

1. Teaching. They learned his doctrine. As you go through Paul's letters, you see how his heart was burdened about many subjects: the Word of God, prayer, holy living, stewardship, the knowledge of Messiah , the Holy Spirit, the End Time, discipleship, leadership in the Congregations, faith, the Gospel of the Kingdom, justification of our lives, and many other related subjects.
2. Way of life. What is the best way to teach your ‘way of life’ to someone else? By letting him see how you live, think, and work. The best way to do this is by allowing someone else to live with you, travel with you, and minister with you. That is how Paul trained Timothy, Priscilla, Aquila, and many others.

3. Purpose. Paul had two God-given objectives in life and he was eager to share them. World evangelization was one. He lived to spread the Gospel. Nothing diverted him from that task. He witnessed in the synagogue and marketplace. He witnessed to his jailers and to his shipmates on a sea voyage. No matter what the circumstances or situation, he witnessed. Paul's second objective was to have a deep personal knowledge of Messiah Jesus. He said, "I want to know Messiah and the power of His resurrection and the fellowship of shar­ing in His sufferings, becoming like Him in his death, and so, to attain to the resurrection from the dead" (Phil 3:10-11).

4. Faith. Now how would a person teach someone else faith-experiences? Paul ‘lived by faith.’ He performed ‘acts of faith.’ From prison he called on others to take courage and ‘keep the faith.’ On board a storm-tossed ship he spoke words of comfort and faith. He displayed faith and courage in the midst of riots and tumult. He communicated faith by word and deed.
The two great enemies of faith are fear and doubt (Mk 4:40; 5:36). If you are presently in the midst of one of life's storms, you can help others to make it through the storm by affirming your confidence in God. Someone who needs your encouragement is always watching you. Remember that Paul and Silas were beaten and thrown into prison. Did they complain or sing protest songs? No! They sang hymns of praise to God (Yahweh), showing an act of faith. As they sang, "the other prisoners were listening to them" (Acts 16:25).

5. Patience. The ability to keep your cool when being mistreated is a form of patience. Paul displayed great patience in bearing all indignities, reproaches, afflictions, and persecutions, for the sake of Christ and his Gospel. Though he was not at all moved by these troubles, he continued with great courage and constancy to the end.
6. Love. Love is the great identifying mark of a faithful saint. While the Lord was on earth he gave his followers a badge to wear that would mark them as His people. He said, "A new commandment I give you: Love one another. As I have loved you, so you must love one another. All men will know that you are my disciples if you love one another" (John 13:34-35).

7. Endurance. This is the Messiah-like quality that does not give in to the circumstances of life or give up when the battle rages. Endurance was one of Paul's key prayer requests for the Colossians: "We pray this in order that you may live a life worthy of the Lord and may please him in every way: bearing fruit in every good work, growing in the knowledge of God, being strengthened with all power according to his glorious might so that you may have great endurance and patience" (Col 1:10-11). It is through this quality of en­durance that God perfects Christian character in our lives (Jas.1:2-4).

8. Persecutions and Sufferings. Although Paul was continually opposed by the enemies of the Gospel, he kept on the attack. In 2 Cor.11:24-26 he says, ‘Five times I received from the Jews the forty lashes minus one. Three times I was beaten with rods, once I was stoned, three times I was shipwrecked, I spent a night and a day in the open sea, I have been constantly on the move. I have been in danger from rivers, in danger from bandits, in danger from my own countrymen, in danger from Gentiles; in danger in the city, in danger in the country, in danger at sea; and in danger from false brothers.’
God’s people are called upon to keep going in spite of sufferings or personal problems. Paul wrote to the Congregation at Corinth about sufferings he faced and how he overcame them. Although Paul also suffered from a thorn in the flesh, he was not discouraged by it. When he prayed and asked God to remove it, God gave him a word of encouragement: "My grace is sufficient for you… For when I am weak, then I am strong" (2 Cor 12:9-10).
Paul taught others how God supplied the strength to overcome the most difficult circumstances in his personal ex­perience. He imparted the content of his training syllabus by word and deeds. These qualities were the basis for the instruction Paul gave growing believers like Priscilla and Aquila.  After spending a year and a half In Corinth, Paul took them to Ephesus where he left them and returned to Antioch. Later Paul resumed traveling around to encourage the disciples.
In Antioch, Priscilla and Aquila met Apollos, a fervent, eloquent man who had "a thorough knowledge of the Scriptures" and "taught about Jesus accurately" (Acts 18:24-25). Rarely do we meet someone as gifted and talented as Apollos who is also willing to learn and be taught. But he only knew the baptism of John, so when Priscilla and Aquila invited him to their home and explained the way of God more adequately (Acts 18:26), Apollos was eager to learn. When he went to Achaia, "he was a great help to those who by grace had believed. For he vigorously refuted the Jews In public debate, proving from the Scriptures that Jesus was the Messiah" (Acts 18:27-28).
