Please read Luke 8:4-21.
Those of use who have listened to God’s Word and are obedient to its commands have open hearts to the Lord. Jesus said that it’s like a gardening example – we are like good soil that, when the seed of the Word of God is cast into it, produces a good crop, with good fruit.
We who have received and accepted the message of the Gospel must share it with others, that they might also have the opportunity to allow the Word of God to change their lives as well. Jesus gave us anther way to picture this – we are like lamps that radiate light into even the darkest corner. It reveals the truth about even the most hidden areas of life.
Lamps themselves cannot change another object into a lamp, but their light can reveal what is already there. Only the Light of the World and an open heart (aka “good soil”) can covert a dark object into a lamp. Only God can transform a person from being wicked to being righteous.
