Why is Jesus so Important?

He is the Son of God:

In the beginning was the Word (Jesus) and the Word was with God and the Word was God (Gospel of John 1:1)

He died on a cross to pay for man's sin:

" … Christ died for our sins according to the Scriptures" ( 1 Corinthians 15:3)

God will accept all who come through Him (see "What is Salvation")

"For God so loved the world that He gave His only begotten Son that whoever believes in Him should not perish but have everlasting life" (John 3:16)

He is the only way to God:

"I (Jesus)  am the Way the Truth and the Life. No one comes to the Father except through Me" (John 14:6)

He will some day return to receive His own to be with him forever:

" .. I (Jesus) go to prepare a place for you, I will come again and receive you to Myself; that where I am there you may be also" (John 14:6)
