Being a believer in Jesus is something that we do, and this is expressed in how we live and not just in a set of beliefs. As we know, the devil believes in Jesus, as well (see James 2:19)

John 1:1–18, describes not only who Jesus Christ, the Word (logos), is but also how people in the world related to Him. In John 1:9

“In the beginning was the Word, and the Word was with God, and the Word was God”

(John 1:1)

In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1)

The life of Christ that gives life to the world is in His word. It was by His word that Jesus healed disease and cast out demons; by His word He stilled the sea, and raised the dead; and the people bore witness that His word was with power.

The weeping over his death (John 11:19, 31, 33); the sisters’ lament that Lazarus would not have died if Jesus had been present (John 11:21, 32); and Jesus’ own tears (John 11:35).

the Pharisees think Jesus is a sinner because He healed on the Sabbath (John 9:16, 24), and they will slander the healed man as “born in utter sin” (John 9:34, ESV)

The disciples made a connection between sickness and sin. A number of Old Testament passages point in that direction (compare with Exod. 20:5, 2 Kings 5:15–27, 2 Kings 15:5, and 2 Chron. 26:16–21)

The Judeans were expecting an earthly messiah who would deliver them from the oppression of the Roman Empire. Two of the most difficult things encountered in war are feeding the troops and caring for the wounded and dead

In John 6:4, 5, the apostle goes out of his way to state that the timing of the feeding of the 5,000 was near the Passover. The Passover was a commemoration of the deliverance of Israel from Egypt
