Acts 18

(10)  For I am with you, and no one is going to attack and harm you, because I have many people in this city.
Christian can feel alone in our daily struggle to exalt God with an abundance of obstacles. Usually however, God provides fellow brothers and sisters in our community who'm we can turn to for spiritual or financial support. 

(27-28) When Apollos wanted to go to Achaia, the brothers and sisters encouraged him and wrote to the disciples there to welcome him. When he arrived, he was a great help to those who by grace had believed. For he vigorously refuted his Jewish opponents in public debate, proving from the Scriptures that Jesus was the Messiah.
Before Apollos discovered salvation he was already known to be a scholar, orator, and debater. If we have an urge to serve Christ while have specific gifts that we aren't utilising for his glory, we should stop hesitating. Apollos major strength was his human reasoning so he convinced many in Greece. Quite often i'm guilty of being sloppy and prideful, knowing that I have sample opportunity to proclaim Jesus salvation to unbelievers.
