"God's grace is the hand which adjusts the switch. It is up to you whether you cooperate and allow the switch to be turned to "max heat". The water heater is like the Holy Spirit, firing us up with the love of God. If we don't cooperate with grace and allow our switches to be moved accordingly, we won't become fired up! If we close ourselves off to God and His love, we will simply be cold water on a winter morning. No one really likes cold showers in the winter! "
