John Piper is on point with this sermon. Christians in the United States are under no obligation to vote. We are citizens of another kingdom and we have no duty in the present to choose between wickedness.
It is worth noting that John Piper says he will not vote for either of the major party Presidential candidates. For those who do not know who John Piper is, he is one of the most influential Christian pastors in the Western hemisphere, if not the world at large.
I am not saying we are bound not to vote. I am saying that the children of God are free to hear the voice of their Master about how to best witness to his supremacy. I will vote. But I have no intention of voting for either of these presidential candidates.
