Hello ,
Once armies carried cannonballs with them, afraid they would meet the enemy somewhere and have nothing to shoot at it.
In terms of specific gravity, grudges are about as heavy as cannonballs, but it makes little sense to carry them. Most likely, the "enemy" is unaware of your
enmity, and surely would be surprised to learn that you've been stalking him with a cannonball in your pocket.
So examine your grudges. Do what armies do when hostilities are over: unload the cannonballs and stack them on the courthouse lawn. Then marvel at how much easier it is to get around.
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." Ephesians 4:31-32
Have a great day and God bless!
