And many came to him. And they said, "John did no sign, but everything that John said about this man was true." And many believed in him there. (John 10:41, 42 ESV)
John the baptist did not do miracles. He had no signs that people would consider miraculous. But he had words. He spoke things about Jesus, telling those things to anyone who would listen. And that was it. Nothing flashy. Nothing "impressive." Instead, he merely spoke things about Jesus to those who would listen.
But the aftermath of his sharing about Jesus brought the miraculous. The result: "And many believed in him there." And there it is. Many believed in Jesus because of what John told them about him. They believed in Jesus.
The same thing is true for us. You may not be doing the things that others consider to be "miraculous," but telling others about Jesus leads to the miraculous of them believing in him. May God use us to usher in the miraculous as we tell others about Jesus and they come to believe in him.
