(1 Timothy 5:23 NIV) Stop drinking only water, and use a little wine because of your stomach and your frequent illnesses.

(Galatians 6:11 NIV) See what large letters I use as I write to you with my own hand!

(2 Corinthians 11:23-28 NIV) Are they servants of Christ? (I am out of my mind to talk like this.) I am more. I have worked much harder, been in prison more frequently, been flogged more severely, and been exposed to death again and again. {24} Five times I received from the Jews the forty lashes minus one. {25} 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, {26} 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. {27} I have labored and toiled and have often gone without sleep; I have known hunger and thirst and have often gone without food; I have been cold and naked. {28} Besides everything else, I face daily the pressure of my concern for all the churches.

(2 Corinthians 8:1-2 NIV) And now, brothers, we want you to know about the grace that God has given the Macedonian churches. {2} Out of the most severe trial, their overflowing joy and their extreme poverty welled up in rich generosity.
