Our culture has turned the cross into a piece of art, a trinket of jewelry dangling about the neck or hanging from an earlobe, a cultural icon instead of the icon of God's love for sinners. Like the people of Paul's day, people today still clamor for displays of power and glory. Miracles are a good drawing card. Do enough of them and you can have your own TV show. We go with whatever works.
Success indicates divine approval in our pragmatic, American way of thinking.
If it works it must be from God. Never mind the cross, Pastor. We need to grow this church. Massage our bruised egos. Stroke our self-esteem.
