Isaiah 65 and 66 speaks of the last days when God will establish new heavens and a new earth. He speaks of judgment upon those who do not follow Him and blessings upon those who fear Him.
God makes an interesting statement: “I was ready to be sought out by those who did not ask, to be found by those who did not seek me. I said, “Here I am, here I am,” to a nation that did not call on my name. I held out my hands all day long to a rebellious people, who walk in a way that is not good, following their own devices;” God is always there calling out to us. Even when we are deep in rebellion God is still there. He is waiting for us to respond to His calls. If we think that He doesn’t care or isn’t close by we are just fooling ourselves. God tells us that He is close. We just have to listen and respond.
We must remember that part of the purpose of prophecy is to change the hearts of those who are in rebellion. It is mainly saying, “IF you continue on this path, this is what will happen.” God is always holding out the promise that if we turn around the outcome of the prophecy can be good rather than harmful. It is supposed to be a wakeup call to let us know we are moving in the wrong direction.
John 1 begins with a beautiful description of Jesus. He is the Word of God, the Word who is God. This means for us that Jesus is the fulfillment of the word of God which we call the Bible. He is every word that God has spoken. These words shine light into the darkness of our souls.
The Holy Spirit revealed to John the baptizer that Jesus is the Lamb of God, the one true sacrifice for our sins. John pointed the way to the Son of God.
People began to follow Jesus. In the telling of the calling of Nathaniel, Jesus reveals that He sees us before we know Him. He knows that we will follow.
The writer of John is definitive from the outset that Jesus is the Messiah, the Son of God and the Son of Man. Where the other gospels wait to affirm this claim, John leads with this point. The rest of the gospel is the working out of just what this means.
