And you, my child, will be called a prophet of the Most High; for you will go on before the Lord to prepare the way for him, to give his people the knowledge of salvation through the forgiveness of their sins.
Zechariah was speaking to his newly born son who would become John the Baptist. Notice what he prophetically speaks to John and ultimately to us: We come to the knowledge of salvation when we understand our sin and the need for forgiveness. We can talk of Jesus being our Savior, but do we realize that means we are not able to change ourselves and need to be rescued? The good news becomes good when we truly realize the state of our souls before God. The birth of John the Baptist reminds us that we are more flawed than we want to admit, but more loved than we could dream. This exposes our fallen nature while embracing the love of God. This empowers us with salvation.
