A teacher once told each of her students to bring a clear plastic bag and a sack of potatoes to school. For every person they refuse to forgive in their lifes experience, they chose a potato, wrote on it the name and date, and put it in the plastic bag. Some of their bags were quite heavy.
They were then told to carry this bag with them everywhere for one week, putting it beside their bed at night, on the car seat when driving, next to their desk at work.
The hassle of lugging this around with them made it clear what a weight they were carrying spiritually, and how they had to pay attention to it all the time to not forget and keep leaving it in embarrassing places. Naturally, the condition of the potatoes deteriorated to a nasty smelly slime. This was a great metaphor for the price we pay for keeping our pain and heavy negativity! Too often we think of being acquitted as a gift to the other person, and it clearly is for ourselves!
Praise the LORD, O my soul;
all my inmost being,
praise his holy name.
Praise the LORD, O my soul,
and forget not all his benefits
who forgives all your sins and heals all your diseases,
who redeems your life from the pit
and crowns you with love and compassion,
who satisfies your desires with good things
so that your youth is renewed like the eagles.
(Psalm 103:1-5)
