To conclude our study of Isaiah chapter six, Darnell focuses on the call God gives to Isaiah: “Go! Say to these people…” (v. 9). In verses 8–13, the Lord commissions Isaiah to be a light in a dark and unresponsive world. For us today, this reveals our calling as believers: to reflect God’s glory throughout the earth for all time. This divine mission echoes the same message found in all four Gospels. Darnell also challenges the idea that simply being “nice” is the same as being a light. If the power of God’s plan rested on human kindness alone, there would have been no need for Jesus to die in our place. The power of the gospel flows from the Creator Himself—we are merely instruments of His grace. All who are in Christ Jesus are called to live life on mission, bringing His light into every corner of darkness. The only question that remains is: will you go?
