The apostle Paul knew the saints of God and desired to greet them by name. This serves as a tremendous demonstration of brotherly love!
A man’s salutation can serve as the initial window to the condition of his heart. To understand this truth, consider Nabal's salutation concerning David.
The Bible often defines words through their associations. For instance, the words salute, saluteth, and salutation involve a greeting.
The Bible associates love with action. In this passage, the Bible speaks of the believer’s love for other believers, relating it to the Lord’s crucifixion. If a Christian knows and recognizes the love of God, it should drastically affect his relationships. He cannot deal with others as the world would because the love of God has formed compassion within in his heart. This matter is so important to the Lord that He provided believers with a scenario to help judge their level of compassion. The book of First John says that if a brother has a need, and another brother can help him with his need, yet refuses, he lacks compassion (see also James 2:15-16). Therefore, one’s deeds, not simply one’s words alone, demonstrate true love!
