Many times I have experienced and have heard from others, how a lesson or sermon has affected someone in a way that was not planned, seen, or intended. God stirred that person and opened their eyes, through His word. And His purpose was fulfilled through what was preached, taught, or shared from His word.
That is part of the mystery and power seen in the preaching of the Gospel, the message of the cross. So do not ever hesitate to share the Word of God; you may be planting or watering a seed, cultivating or nurturing a young plant, or even bringing it to harvest. God’s Word never goes out empty.
