These men in Antioch also show us that there's no mold to fit into. There's no entrance exam that forces you to prove your intelligence or strength or that determines how good of a fit you are or are not based on your opinions or skills; there's merely examination of how your soul is in need of Jesus's salvation. Your background doesn't discount you. Your experiences do not disqualify you. Where you're coming from, figuratively and literally, doesn't make you unfit for God's kingdom. In fact, God's kingdom longs for your voice.
If there was ever a situation to worry, it would've been Peter's, but he was untouched by worry. He surely believed God would make a way if God wasn't done with him. His faith wasn't shaken by Herod's hateful actions or the people's encouragement of them, even after the brutal death of James. Peter was steadfast in his faith because he knew God was faithful.
A great number became believers. Not just good people. Not just those with high-paying jobs and benefits. Not just the household names or the educated or the ones without baggage. All kinds of people from all walks of life came to know God. Thank God for Some Men of Cyprus and Cyrene because through their actions, we see that God's love runs just as deep and pure for normal people as it does for those we think are important.
I wish I could say that this is all a thing of the past, that we as members of the Church aren't still tempted to only speak of God's grace to those we like. The truth is, each of us tend to be very selective in who we think God's infinite grace should be extended to, forgetting that none are worthy and all are valued by God. We act like bouncers at the altar, only wanting the ones we approve of to come into the kingdom of God. And Peter's actions in Acts 10 show us just how wrong we are.
