Light.

WHEN Pilgrim was told to go to the wicket-gate to be saved, and was pointed to it and asked, “Could he see it?” he answered, “No!” For sinners cannot see Jesus.
“But,” said Evangelist, “Canst thou see a Light?”
“Yes, I can see a Light,” said the pilgrim, “for the Word of God is plain, and open to the seeking soul.”
“Then follow that Light, and it will lead to the wicket-gate.”
Jesus said: —
“I am the door: by Me if any man enter in, he shall be saved, and shall go in and out and find pasture.” —John 10:99I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. (John 10:9).
