Paul was no stranger to difficulties, hardship, and persecution, but, because of the importance of his ministry and the power and strength of God, he didn't lose heart. Instead of complaining about hardships and what he didn’t have, he keeps his focus on what He does have in Christ. We should do the same.
Moses came with the ministry of death carved in letters in stone, but Paul presents the ministry of the Spirit which brings life. And where once men were left with a veil over their heart, we, with unveiled face behold the glory of the Lord and are being transformed!
Paul's decision to not visit the Corinthians was made in great pain and anguish. Today we see Paul explain in greater detail why, in order to not cause them any additional pain, that he didn't visit as expected. He also encourages forgiveness to the one who seems to have caused this painful situation.
As we continue on in our study of 2 Corinthians, it appears that those who would undermine Paul are saying that he is inconsistent, saying one thing but doing another. They also question his ministry and teaching. In the second half of chapter one, Paul begins defending his ministry and his decisions.
