Repent.

All throughout the bible we see God telling us the need of repentance.  For without it salvation can never be obtained. Ezekiel 18 (NIV) gives us a very direct, real, practical explaination of what happens if a person does not live a life of repentance. 

Ezekiel 18:25-32

25. "Yet you say, 'The way of the LORD is not just.' Hear, you Israelites: Is my way unjust? Is it not your ways that are unjust? 26. If a righteous person turns from their righteousness and commits sin, they will die for it; because of the sin they have committed they will die. 27. But if a wicked person turns away from the wickedness they have committed and does what is just and right, they will save their life. 28. Because they consider all the offenses they have committed and turn away from them, that person will surely live; they will not die. 29. Yet the Israelites say, 'The way of the LORD is not just.' Are my ways unjust, people of Israel? Is it not your ways that are unjust? 30. "Therefore, you Israelites, I will judge each of you according to your own ways, declares the Sovereign LORD. Repent! Turn away from all your offenses; then sin will not be your downfall. 31. Rid yourselves of all the offenses you have committed, and get a new heart and a new spirit. Why will you die, people of Israel? 32. For I take no pleasure in the death of anyone, declares the Sovereign LORD. Repent and live!  Don't worry about what someone else is doing.  Instead repent and concern yourself with your own issues that you too might receive your crown from God The Father through Christ Jesus our Savior and Lord.
