Short but sweet:
Often we are all too convinced of our own holiness and lack of sinfulness because we compare ourselves to other historical figures. We must remember that God's standards are not ours, and that the standard we must measure up to is Yeshua. None of us are good, no, not one, and our righteousness in his sight is as filthy rags. Only Yeshua can give us the power to go and sin no more.
