The gift of the Holy Ghost as a talent

Think of the gift of the Holy Ghost as a talent (it must be exercised or practiced)

Brother Aird compared the Holy Ghost to air in a jar. We don’t see it and many people would call the jar empty. The gift of the Holy Ghost is like being given a lid on the jar. With a tight lid the air is not replaced in the jar as soon as the jar is taken to a hostile environment (underwater, pollution, space).
