Ephesians 4:17-19 (NLT)
17 With the Lord�s authority I say this: Live no longer as the Gentiles do, for they are hopelessly confused. 18 Their minds are full of darkness; they wander far from the life God gives because they have closed their minds and hardened their hearts against him. 19 They have no sense of shame. They live for lustful pleasure and eagerly practice every kind of impurity.

The Apostle, speaking by the authority of Christ, tells the Ephesians to change the way they live. They should no longer live as not knowing God, but live as people who are close to God. Their minds and hearts should be open to God and not closed like those who do not know God. For those who do not know God allow the darkness of sin to harden their hearts so that they follow after their own desires.

In July of 1945, the battle cruiser USS Indianapolis was returning from the mission when it was hit by a torpedo. Quickly sinking, in 12 minutes three hundred of the twelve hundred men died. The remaining 900 were left in the ocean without food or water; 316 survived. Many died from the temptation to drink the ocean water. The chief medical officer recorded how he tried to stop the men from drinking the ocean water knowing they would quickly perish. He slapped those who became manic in an attempt to bring them back to a state of sanity. Yet men drank the ocean water thinking they were quenching their thirst only to find out they were hastening their death. Many today try to quench their thirst with sin. They think their indulgence will bring satisfaction; but in reality it only hastens death.
