John 3:16, the most famous verse in the Bible tells us that:

“God so loved the world that He gave his only begotten that whoever believes on Him would not perish but would have everlasting life”

This verse tells us three things about the person and work of Jesus:

1.He is the Son of God, in fact, Jesus is God in the flesh- John 1: 14, 18.

14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

18 No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him.

2. He is the Savior of the world- Matt. 1:21.

21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.

3. He is the source of life- John 1:3-5.

3 All things were made by him; and without him was not any thing made that was made. 4 In him was life; and the life was the light of men. 5 And the light shineth in darkness; and the darkness comprehended it not.
