Paul travels from Athens to Corinth on his journey. While in Corinth Paul has a vision from the Lord, the Lord tells him, "Do not be afraid; keep on spreaking, do not be silent. For I am with you, and no one is going to attack and harm you, because I have many people in this city." (Acts 18:9-10)
When we find ourselves afraid we can become paralyzed, but this is when we need to continue to keep our focus and attention on God. If we're fearing (trusting) God we can see God for who He is and fear people less.
