Charles Spurgeon Commentary Matthew 13:6

"and when the sun was risen, they were scorched; and because they had no root, they withered away." — Matthew 13:6 (ASV)

And when the sun was up, they were scorched; and because they had no root, they withered away

They seemed to be alive at the top, but they were really dead below. How many there are of that sort still; they make a bold profession, but it is only for a while, and then they wither away.
