Jesus teaches the people something new about forgiveness

Many of us were taught to drive using the "Ten and Two" method of hand placement on the steering wheel. We were also told that the best way to turn the steering wheel was a hand over hand motion towards the top.
That is how I learned. Then I got into an accident a couple years back and doing some 'driving school' remediation I learned that was now wrong.
It is "Nine and Three" and you turn under the steering wheel (at the bottom).
WHAT!?

Well, yes, for it is no longer needed to do it that way and you could get hurt.
Why? Airbags and other advancements.
Hand over hand at the top was needed for all of the vehicles we used to drive that were not power steering and you needed all of the leverage and control you could muster.
Plus, if you are hand over hand, or merely at 10 and 2 and the airbag goes off you could hit yourself in the face with your own arms and hands.

Was what many of us taught wrong? No.
However, it is no longer necessary and in some cases harmful.

Jesus teaches the people something new about forgiveness in the Gospel for Sunday. You are to forgive, yes, but only to a limit.
Peter understood that in Jesus, that limit should be higher. Grace- right?

Yet Jesus teaches us that grace is not keeping count, no matter the number.  It isn't about keeping track or keeping score. Following Jesus is about knowing grace that never ends (otherwise is it really grace if there's even a limit on supply?), and extending that grace.
It seems to me, like I think it seemed to Jesus, that the issue wasn't a shortage in the supply of grace, just in the number of users and sharers. 

How might you invite others to live in GRACE, and how might you grow in your receiving and sharing of it?
