There is a Hell.  Jesus makes reference to it about 60 times in the Gospels.  (Having said that, Jesus makes about 3 times more references to Heaven.)

The Feeding of the 5000 (men, plus additional women and children) was a real miracle of Jesus.  To say otherwise is to deny the divinity of Christ.

When we keep our eyes on Christ, we can do more than we ever could without him, as Peter discovered. (14:39)  When we doubt Him, we will “sink.” (14:30)
