1 John 4:14
St. John as an Eyewitness to Jesus
14 And we have seen and testify that the Father has sent his Son to be the Savior of the world.
2 Peter 1:16
St. Peter as an Eyewitness to Jesus
16 For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty.
St. John and St. Peter were Disciples of Jesus for three years...And they were eyewitnesses to Jesus...They both would write about their being eyewitness to Him and His teachings...Both of these Saints tell us they saw Him and testify that He is the Christ...They saw the Messiah and what He can do...The Christ, the Messiah was the one to come...He is the Son of God and the Savior of our world...
