Matthew 18:8-9

1 Corinthians 9:27

but I beat down my body, and bring it into subjection, that I may not by any means, after having preached to others, myself become reprobate.

Philippians 3:19

whose end is perdition, whose God is their belly, and their glory in their shame, whose minds are occupied with earthly things.
