We don't want to block the flow of forgiveness.
"For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses." - Matthew 6:14-15 ESV
Sometimes when I see narrow stretch of road, a one lane roundabout or a new narrow on or off ramp I drive on it and think, 'I hope no one breaks down here. How will anyone else get by if they do?'
Somehow if we block a person's access to what we freely receive the access is blocked off for us as well.
Like a morning commute... forgiveness is a shared but individual experience.
As I have said before, grace is something that flows one way from God to us. It isn't a two way street.
Imagine us blocking this narrow road in our own mind out of spite so another can not pass but at the same time we are prevented from going anywhere? We keep a person prisoner but get stuck with the job of being their jailer in the midst of honking and beeping and it is all happening inside our soul.
God's grace is flowing out from Him in every direction with the possibility of it reaching every person or situation if the opening can be found for it to come in. Like water it goes to the low places to fill them to overflowing.
"He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water." - John 7:38 KJV
I want to live in the emotional release of forgiveness as a conduit of that flow not blocking it.
"Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it." - Matthew 7:13-14 NKJV
God seems to like these narrow passageways. Perhaps it keeps life a little more personal.
