"In the beginning was the Word, and the Word was with God, and the Word was God." John 1:1
"The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth." John 1:14
When John begins his Gospel he hearkens to the opening verses of Genesis. But with one big difference - Genesis starts "In the beginning" but John looks back before the beginning!
His Gospel builds one of the clearest and best presentations of the Salvation Story. How can you can build a compelling case for Jesus being the Savior for sinners if you don't establish that He is truly the Son of God?
John establishes Jesus divine credentials by presenting Him and co-existence and co-equal with God!
Wow! That's bold!
To borrow from Josh McDowell; for John to make such a daring claim as Jesus being God he would have to be a lunatic, or a liar, OR he must have been absolutely convinced about Jesus.
John 1:1 and John 1:14 very concisely declared the story of salvation. Watch what happens where the two verses are superimposed:
"In the beginning was the Word" (V. 1a) - "The Word became flesh and made His dwelling among us" (V. 14a)
"and the Word was with God" (V. 1b) - "we have seen His glory, the glory of the One and only Son" (V. 14b)
Thank you, Jesus!
"and the Word was God" (V. 1c) - "who came from God, full of grace and truth" (V. 14c)
How good is that?
