"For example, John 3:16 without 3:17 seems to balance itself in the wrong place. John 3:17 says "For God did not send his Son into the world to condemn the world, but that the world through him might be saved." This verse gives me greater clarity into how to read the one that comes before it. It tells me that if Jesus did not come into the world to condemn it, then neither should Christians. The use of the word "might" in the final clause, "that the world through him might be saved," tells me that the domain of Christian witness is not salvation (that is God's work), but service - selfless love and sacrifice. John 3:16 standing alone with the theology of care offered in John 3:17 makes it harder to interpret."
