'A person who misuses God's name will not be held guiltless by the Lord' (Exodus 20:7). Does this verse indicate that those who take Gods name in vain have committed an unpardonable sin: If this is the case, mankind God is in dire straits. I would imagine most men have taken Gods name in vain in one form or another. How is a man to get into heaven if he/she stands before God thinking that his sins (all inclusive) are not forgiven.
Exodus 20:7
ESV - 7 You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes his name in vain.

Everyone is guilty before God for a myriad of reasons and hence deserving of death. Fortunately, Jesus was sinless and acts as the believer's High Priest, applying His own blood to cover our sin and imputing His own righteousness to us.
So God doesn't look at us and our looong list of sins, but rather looks at Jesus' sinless perfection and declares us 'not guilty' for His sake.
