For they have made ready their heart like an oven, While they lie in wait. Their baker sleeps all the night. In the morning it burns as a flaming fire.
You remember Samson when he said, "I will rise up as I did before," and he knew not that the Spirit of God had departed from him. Tragic when people are still going on with motions but God has left and they're not even aware that God is gone because the motions are still there. We're still doing the right thing, we're still doing the religious thing, but what's in your heart? They knew not that their strength were gone.
