Paul was a man motivated by love and concern for others, especially his fellow brothers and sisters in Christ. This is evident from his life of ministry, going to various congregations to preach to them, writing letters, and sending his companions when he couldn’t go himself to help them during trials or difficulties. One example of this is 1 Thessalonians 3:1-3:
“Therefore, when we could no longer endure it, we thought it good to be left in Athens alone, and sent Timothy, our brother and minister of God, and our fellow laborer in the gospel of Christ, to establish you and encourage you concerning your faith, that no one should be shaken by these afflictions; for you yourselves know that we are appointed to this.”
Can you imagine a love for your brethren so strong that concern for their well being troubles you beyond the point of endurance? So, Paul sent Timothy to help them by establishing them in the faith, and encouraging them.
He did not want their faith to be shaken. It is the lot of all of us to suffer tribulation. The help of our brethren can aid our maintaining faithfulness despite such trials.
To our point, do you have the same love for your brethren that Paul exhibited? We are spiritual family! (cf. Matthew 12:46-50).
