Luke 8:5 A sower went out to sow his seed: and as he sowed some fell by the wayside; and it was trodden down, and the fowls of the air devoured it.
We never read that this sower tried to scare away the birds, or that he stopped to question why the seed did not take hold. No, he just kept on doing his job.
If some people hear the gospel, and do not believe it, does this negate the gospel? Not in the least. The heavenly seed is able to bring life; their souls are just hardened.
Please come over into this field, and help us to sow the gospel. Some seeds will fall by the wayside, but others will fall upon good ground.
