Isaiah’s visions of Zion give the Church a clear sense of our marching orders. We are to be the light of the world, a city set on a hill. Consequently, we must be equipped as God’s people to bless the nations of the earth by articulating the Gospel. And this is precisely what Peter tells us. We are always to be ready to give a reasoned defense for the hope that is in us. So what does all this mean and how can we be godly evangelists?
