One of the great theological truths of our faith is that we are each one responsible for our own actions. Scripture teaches quite plainly that we will individually answer for our behavior and our attitudes and our heart.
That truth, of course, is both good news and bad news at the same time.
The good news is that God won't hold me accountable for your actions - or hold you accountable for mine.
The bad news is that I have plenty of my own junk to deal with.
And while I am sobered by my own shortcomings and sin, I am sincerely grateful that I won't have to answer for the shortcomings and sins of others. We can all be thankful for that.
The concept is called personal responsibility.
