When the Jews in Corinth opposed the gospel of Jesus Christ, that Paul was preaching in the synagogue, Paul informs them that he would go now to the Gentiles and he leaves and goes to man named Justus. From this account we can learn that Justus was hospitable and he allowed Paul to stay with him. Not much is said of Justus, but what is said has voluminous significance. As the Bible introduces this character, it qualifies, him as being a worshiper of God (Acts 18:7) .

What can we learn from Justus?
We must be hospitable and willing to host God’s people as needed, for the ministry of God to continue. More importantly, if someone was to describe us, would they describe us a “worshiper of God”?  Think about it.

Acts 18:4-7 (KJV)
4
And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
5 And when Silas and Timotheus were come from Macedonia, Paul was pressed in the spirit, and testified to the Jews that Jesus was Christ.
6 And when they opposed themselves, and blasphemed, he shook his raiment, and said unto them, Your blood be upon your own heads; I am clean; from henceforth I will go unto the Gentiles.
7
And he departed thence, and entered into a certain man’s house, named Justus, one that worshipped God, whose house joined hard to the synagogue.
