When you hold grudges, your hands aren’t free to catch blessings. (Source unknown)

Someone else said it this way: “Let your hands be so busy catching blessings that you don’t have the capacity to hold on to grudges.” Another: “Holding a grudge is like letting someone live rent-free in your head.” A spirit of unforgiveness will keep you from enjoying life; don’t let the sun go down without ridding yourself of resentment.

Resentment kills a fool. (Job 5:2) The Lord’s servant must not be quarrelsome but must be kind to everyone . . . not resentful. (2 Timothy 2:24)
