Charles Spurgeon Commentary Luke 8:15

"And that in the good ground, these are such as in an honest and good heart, having heard the word, hold it fast, and bring forth fruit with patience." — Luke 8:15 (ASV)

Or, "with perseverance, with continuance." He that endureth to the end, the same shall be saved. He is not converted at all who is not converted eternally. The work of man is temporary; the work of God is everlasting.
