“But the wise took oil in their vessels with their lamps.”
King James Version (KJV)
25:4 The wise took oil in their vessels - Love in their hearts. And they daily sought a fresh supply of spiritual strength, till their faith was made perfect.
Mt 25:4 But the wise took oil in their vessels. In this their wisdom was displayed. They not only "let their light shine" (Mt 5:16), but at the same time kept the grace renewed that was essential to the continuance of their light.
