Some of these newfangled inventions are great-especially the puncture-proof tire. If you are driving along with ordinary tires and a nail goes through one of them, whis-s-s, you lose all the air. But a puncture-proof tire is different if a nail goes through, there is some stuff inside that runs around and stops the hole and the air stays in.
The heart of a Christian is like that puncture proof tire. An ordinary heart may be filled with love, but when someone does something to puncture that heart, all the love runs out and hatred and hard feelings take its place. But a puncture proof heart is different. It is filled with the Spirit of Christ and when someone, through their words or deeds punctures that heart, immediately the hole is stopped up tight and the love stays in.”
