Light is sown like seed for the righteous, and gladness for the upright in heart. Psalm 97:11
What the Bible says about light and seed
The True Light "In him, (the Lord Jesus) was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it. The true light that gives light to every man was coming into the world,…the world didn’t recognize him." John 1:4,9.
The Good Seed and the Weeds “The kingdom of heaven is like a man who sowed good seeds in his field. But while everyone was sleeping, his enemy came and sowed weeds among the wheat and went away.”Matthew 13:24,25.
