I came across the following graphic.
I have to disagree. What Jesus said means that you can't take that position and follow him.
Shore's analogy fails because Jesus said that the rain comes down on the just and the unjust. God is definitely not with the unjust so having water in your cup doesn’t mean you have God. If you want to argue that Jesus is wrong, then you have to deny that God is in Christianity and you have to abandon Shore's statement. Shore is wrong. Jesus is right.
