Romans 5:12-21 (New Living Translation)
   12 When Adam sinned, sin  entered the world.  Adam’s sin brought death, so death spread to  everyone, for everyone  sinned. 
13  Yes, people  sinned even before the law was given. But it was not  counted as sin  because there was not yet any law to break. 
14 Still, everyone died—from  the time of Adam to  the time of Moses—even those who did not disobey an  explicit  commandment of God, as Adam did. Now Adam is a symbol, a  representation  of Christ, who was yet to come. 
15  But there is a great difference between  Adam’s sin and God’s gracious  gift. For the sin of this one man, Adam,  brought death to many. But even  greater is God’s wonderful grace and  his gift of forgiveness to many  through this other man, Jesus Christ. 
16 And the result of God’s  gracious gift is very  different from the result of that one man’s sin.  For Adam’s sin led to  condemnation, but God’s free gift leads to our  being made right with  God, even though we are guilty of many sins. 
17 For the sin of this one  man, Adam, caused  death to rule over many. But even greater is God’s  wonderful grace and  his gift of righteousness, for all who receive it  will live in triumph  over sin and death through this one man, Jesus  Christ. 
18 Yes, Adam’s  one sin brings  condemnation for everyone, but Christ’s one act of  righteousness brings a  right relationship with God and new life for  everyone. 
19 Because one  person disobeyed  God, many became sinners. But because one other person  obeyed God, many  will be made righteous.
 
20  God’s law was given so that all people could  see how sinful they were.  But as people sinned more and more, God’s  wonderful grace became more  abundant. 
21 So just as  sin ruled over all people and  brought them to death, now God’s wonderful  grace rules instead, giving  us right standing with God and resulting in  eternal life through Jesus  Christ our Lord.
Man's sin...guilt. GOD's gift...grace.
So,  it seems we have a choice to make. We can run from GOD, hide in our  shame and guilt,or...we can turn to GOD and receive HIS wonderful grace.  It's a free gift that some people choose not to except. If that is your  choice then death will be your end. Not only death in this lifetime but  you will be separated from GOD for all eternity. To me it seems the  obvious choice to make would be grace...life. 
Like many others out there that was not always my choice. For years I  choose guilt. Sometimes because of our bad choices we are filled with  guilt and shame. Only GOD can help us to get rid of those feelings about  ourselves. Once we let GOD cover our guilt with HIS grace we have to  let those feelings go. Then we need to move on and make grace our choice  from then on. Admit to HIM when you sin and ask for HIS forgiveness. HE  will give you HIS grace and you have to receive it through faith. As  long as you have the grace of GOD that will be all you need.
2 Corinthians 12:9 (New Living Translation)
9 Each time he said, “My grace is all you need. My power works best in  weakness.” So now I am glad to boast about my weaknesses, so that  the power of Christ can work through me.  
 
Ephesians 2:8 (New Living Translation)
8 God saved you  by his grace when you believed. And you can’t take credit for this; it  is a gift from God.   
To me it all ties back into our relationship with GOD. The more we build  our relationship with GOD the more faith and trust we have in HIM. Then  we aren't afraid to go to HIM and ask for HIS grace when we have done  something we should not have done. Don't fall back into your old habits  of denial and rebellion. Receive HIS forgiveness and forget the guilt.  Go on living the life you were born to live!
