Paul was keenly aware that none of his suffering or service to God was unseen by God. Simply and significantly, he knew that he was appreciated. This allowed him to press forward and spite of harsh criticism, lonely ostracism, and brutal opposition. It also made him more appreciative of servant-hearted Christians and compelled him to encourage them by saying often that both he and God appreciated them.
