Of them the proverbs are true: “A dog returns to its vomit,” and, “A sow that is washed returns to her wallowing in the mud.”
2 Peter 2:22 NIV
“So then as through one transgression there resulted condemnation to all men, even so through one act of righteousness there resulted justification of life to all men.”Romans 5:18 NASB
Do you not know that those who run in a race all run, but one receives the prize? Run in such a way that you may obtain it. And everyone who competes for the prize is temperate in all things. Now they do it to obtain a perishable crown, but we for an imperishable crown. Therefore I run thus: not with uncertainty. Thus I fight: not as one who beats the air. But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified.
I Corinthians 9:24-27 NKJV
