Dan,
There is nothing new about that.
There seems to be very little discussion of this part of the thread title. It deserves better, certainly better than I can render, but...
My take on repentance makes a distinction between self-hatred and sincere regret for one's actions or lack of action. God forgives those who repent. In other words, your participation is necessary in the process of forgiveness.
As a nation, where we've been wrong, we should repent...no we MUST repent to be granted God's grace. It has to happen. If we've done His will, He knows, too.
Do we go off on a "We're so bad, God could never forgive us." funk? No. Repentance and forgiveness are both an end and a new beginning. Realization of error and sin should lead to repentance. Repentance should lead to a new heart that strives to do the things expected of us. "Love the Lord with all our heart, our soul and mind....and love our neighbor as ourselves."
God keeps score, but we're the one's running up the total. He is merciful and willing to forgive...if we're willing to admit it when we're wrong. The need for repentance existed before the WTC attack, it exists now, it will exist tomorrow. We're just not perfect. So, until we are, repentance will be a necessity. Thanks for reading.
