The King James Version of the Bible renders this verse as "with his word". Jesus cast
out spirits or devils with His word. Farther in this gospel we read again of how Jesus
cast out devils: “But if I cast out demons by the Spirit of God, surely the kingdom of God
has come upon you.” Matthew
“The less of idle words we speak, the more our words will be clothed with power.”
This brings us to something else. If Jesus cast out devils by the Spirit, why don't we
have the same results? The problem is that we are full of idle words. Corrupt
communications are rife in the lives of many believers. Think of it this way. Imagine that
you open a bottle of coca-cola, and hold it under a running tap. The water will gradually
dilute the content and it will no longer taste like coca-cola. If you sustain the process
long enough, it will get to a point where all you have in the bottle is water. This is the
point: idle words pollute and dilute. The less of idle words we speak, the more our words
will be clothed with power.
