Galatians 6:10-11. “As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith. Ye see how large a letter I have written unto you with mine own hand.”
Paul wrote this letter from prison. He had very little freedom of movement, and apparently he did not have his usual access to an amanuensis, or scribe. Most of his epistles were dictated. This one, he wrote with his own hand, and it must have been difficult. We know his eyesight was failing. The idea that his comment refers to the extremely large size of the actual letters is not founded on anything in the manuscripts or in any scripture text. He was simply pointing out that what he had to say was so important that he decided to go ahead and write the letter himself, without his usual secretarial help.
He also admonished the Philippian believers to be sure, whenever they had the opportunity, to treat all people well, and especially fellow believers. Be generous, he said. Be liberal in giving and helping. Uphold each other in word and deed.
Love one another.
