In the Bible, oil represents the Holy Spirit. He provides a hedge against undue friction and keeps us running smoothly. People, like Tonka, need to have plenty of oil. The oil needs to be confined to the proper area. Loss of oil will seriously affect life expectancy and performance.
People are a little different.
While we re designed to operate with a certain amount of pressure, too much pressure will constantly seek to escape. We often lose the fruit of the Spirit as it blows. People often get severe headaches, ulcers, and suffer from hypertension. They angrily lose control which can lead to verbal, emotional, and physical abuse of spouses and children. We can t keep pressure from happening.
