The book of John tells the story of Jesus Christ, who is the Word of God and the Son of God, and has existed before all things. Jesus came to earth, performed many miracles, and taught about the kingdom of God, but was not recognized by the world. He called his disciples and revealed his divine nature to them, and eventually was arrested, tried, and crucified, but was resurrected on the third day and appeared to his disciples, giving them the Holy Spirit and instructing them to feed his sheep.
