Christianity teaches the forgiveness of sins by God, but from the Ten Commandments in Exodus (NIV) it says something along the lines of:
"You shall not take the name of the LORD your God in vain; for the LORD will not hold him guiltless that takes his name in vain."
Does this mean that breaking the commandment should be taken as unforgivable by God?
If this sin is unforgivable what implications does that have at the time of judgement?
