Three notable men are not prominent in the scriptures but they were vital in the spreading of the gospel, Aristarchus, John Mark, Justus.
Aristarchus became a prisoner because of his faithfulness to the gospel. He was attacked by an angry crowd because he was a friend of Paul's (Acts 19:29). He was with the group of men who went into a city to get things ready for the the evanelgist (Acts 20:4-5). Another friend of Paul's was John Mark, the cousin of Barnabas who had failed his first missionary journey (Acts 12:25; Acts 15:36-40). But later he proved himself a faithful servant of God as shown by the fact that he again traveled with Paul. And finally a man named Jesus but called Justus who also was a comfort to Paul in his ministry.
Like these men, our part may be small, but God has placed us exactly in the body of Christ where he needs us to be. We can be content where we are and strive to be the best at the responsibility God has given us to do.
Gigantic ships the size of football fields can be seen from a warf. We forget it is the smallest of screws, nails and soldering that holds the ships together. Our task in the body of Christ may seem small, but God knows the importance of why he has placed us exactly where we are.
