“Give my greetings to each of God’s holy people—all who belong to Christ Jesus. The brothers who are with me send you their greetings. And all the rest of God’s people send you greetings, too, especially those in Caesar’s household.” – Philippians 4:21-22 NLT

Here at the end of Philippians, Paul shows the genuine solidarity, love, and excitement the people of Christ have for each other. Everyone is excited to greet each other and send greetings back. We ought to have that same passion for others we see here where we want to say hi and greet other believers when we can out of genuine love for them.
