Once when Paul was in great need, in chains for his confession of the truth, his fellow Christians sent him what was necessary for his wants and needs. He thanked them with these words: You have done well to share in my needs. It is true that I have leaned to be self-sufficient in whatever circumstances I find myself. I know what it is to have plenty and I have learned how to endure privation. I can do all things in him who strengthens me. Still you have done well to send things for my use. Just as this indicates in what sense they had done well, it also shows what Paul himself sought, namely, to avoid being numbered among those who feed themselves and not the sheep. For he does not so much rejoice at his own deliverance from need as he does at their generosity. What then was he seeking? I do not set my heart upon gifts, he says; all I seek for is the fruit of my labor. Not that I may be filled, he says, but that you may not remain empty.
