Jesus said very clearly that "you're either with me or you're against me."
"He who is for us is not against us." "Whoever is not with me is against me, and whoever does not gather with me scatters." (Luke 11:23)
John MacArthur's grandpa said this important truth in a simple way that we will all do well to consider. He said "There are only two groups of people in all the world, and everybody is in either one or the other group. The saints and the aint's." Which are you in? There are no fence sitters.
