HOW TO BE A WITNESS FOR JESUS
INTRODUCTION
The Christian life is not a spectator sport; Jesus did not choose believers to stand idly by while the world continues on its way to hell. On the contrary, His explicit command is, “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age” (Matt. 28:19–20; cf. Luke 14:23).
When believers proclaim the gospel, those who respond savingly to it become fruit that will remain forever (cf. 4:36; Luke 16:9)
SERMON
I. WE MUST RECOGNIZE GOD’S UNIVERSAL CALL
II. WE MUST BE PREPARED FOR QUESTIONS
III. WE MUST BE PREPARED TO HUMBLE OURSELVES AND EXALT CHRIST
If I had been John, I would have probably said something like, “I’ll tell you who I am: I’m the last of the Old Testament prophets. My birth was declared to my father by an angel. The Holy Spirit empowered me for this mission when I was still in the womb. The Son of God called me the greatest man ever to walk the face of the earth [Matt 11:11]. That’s who I am! Who are you?”
Instead John points the conversation to Jesus. When they ask who he is, he tells them who he’s not. “I am not the Messiah.” John wants to make sure no one confuses him with Jesus. He doesn’t draw attention to himself but directs it to Jesus. When they ask him what right he has to baptize, he doesn’t defend himself. He points to Jesus, and when he points to Jesus, he says in essence, “I’m not the one you need to know about. I’m a lowly servant—unworthy even to buckle Christ’s sandal. He’s the one you need to know.”
The great goal of the church is to point the world to Jesus Christ. We gather on Sundays to worship him and learn about him, but then we go out to share him with others.
