Please do not think that greeting others is insignificant. Paul filled the last chapter of the Letter to the Romans with greetings. The Holy Spirit included those greetings for a reason. Read the greetings and see what Paul said about each person and what various ones meant to him.
Romans 16:3-16 shows the many greetings. Listen to how he concluded this section, “Greet one another with a holy kiss. The churches of Christ greet you” (Romans 16:16).
Let us do as the Holy Spirit directs.
