Shortly after writing his first letter to the Corinthians, Paul left Ephesus, where intense excitement had been aroused against him, the evidence of his great success, and proceeded to Macedonia. Pursuing the usual route, he reached Troas, the port of departure for Europe. Here he expected to meet with Titus, whom he had sent from Ephesus to Corinth, with news of the effects produced on the church there by the first epistle; but was disappointed (1 Corinthians 16:9; 2 Corinthians 1:8; 2:12, 13). He then left Troas and proceeded to Macedonia; and at Philippi, where he delayed, he was soon joined by Titus (2 Corinthians 7:6, 7), who brought him good news from Corinth, and also by Timothy. Under the influence of the feelings awakened in his mind by the favourable report which Titus brought back from Corinth, this second epistle was written. It was probably written at Philippi, or, as some think, Thessalonica, early in the year AD 58, and was sent to Corinth by Titus. This letter he addresses not only to the church in Corinth, but also "to the saints which are in all Achaia", i.e., the Roman province of Achaea.
\1. Paul speaks of his spiritual labours and course of life, and expresses his warm affection toward the Corinthians (chapters 1-7).
\2. He gives specific directions regarding the collection that was to be made for their poor brethren in Judea (8, 9).
\3. He defends his own apostolic claim (10-13), and justifies himself from the charges and insinuations of the false teacher and his adherents.
