Isn't John the Baptist's humble statement, "the thongs of whose sandals I am unworthy to untie," a bit overstated? Are we unworthy to serve Christ? If so, why? If not, why not?The bible tells us that Jesus is the unique Son of God. That means He is on equal footing with God. He assumes the authority to forgive sins. This makes it clear that Jesus has all the characteristics of God: the Messiah, Creator of heaven and earth and everything that is in it. Mighty in power, glorious in holiness and fearful in places. He is the King of the whole of the universe. morally perfect, just and fair. He is changeless, and His kingship will last forever. John know that Jesus is the Messiah who can forgive him his sins and grant him salvation.
Therefore John's humble statement isn't overstated but very true.
Are we unworthy to serve Christ? If so, why? If not, why not?
Since Adams rebellion against God, human nature is to disobey Him. Our sins cut us off from God. Romans 3:10 says no one is righteous, not even one. And Romans 3:23 also says "for everyone has sinned. We all fall short of God's glorious standard". However, we give thanks to God for sending Jesus when we were utterly helpless to come to the world as human, to take our place on the cross so that our sins can be forgiven. Anyone who comes to faith and believes in Christ has been washed clean by the blood of Jesus. This means their disobedience has been forgiven, and sins put out of sight. Therefore, since we have been made right in God's sight because of our faith in Jesus, we are worthy to serve Christ.
