God says over and over in the Bible, "Do not be afraid."
There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love. (1 John 4:18)
If you are going to a new place, who do you trust for directions? Someone who was made the journey. Even the Quran testifies to Jesus making the journey to Allah. If he's been there, and knows the way, who will you trust to discover the journey to the One Creator God?
Jesus (Ciise) can be trusted, he's made the journey. The Injiil is full of news about what Jesus has done to get us back to God forever.
Jesus answered, "I am the way..." (John 14:6)
