As a kid, I found this phrase from the Our Father a bit curious.
I first learned the prayer with the word trespasses in it, as quoted below:
forgive us our trespasses as we forgive those who trespass against us.
Although I ran through the woods quite a bit, I never violated any “No Trespassing” signs. So I thought myself quite safe.
Now a bit older I realize this portion of prayer is not so safe at all. Augustine called it “The terrible petition“. For if we utter it with an unforgiving heart, we are asking the Lord NOT to forgive us.
