Letting go of bitterness of spirit needs a decision by us to cooperate with God's grace and to let go. No matter how troubled and bitter we may be, we have a built-in, God-given ability to make decisions. We will have to make this decision more than once, perhaps many times, before our dark thoughts and feelings become less frequent and intense. Then though they reappear from time to time they will be much more manageable.
After placing ourselves before an image of the Lord—a crucifix or picture—we can begin a dialogue with Jesus. The image, of course, will speak only in our understanding and we will hear only what we already know. Still this will reinforce the wisdom we have learned in former dialogues. Jesus will say to us: Let it go! As we do “let it go” we will harvest three fruits: our hearts will find peace; we will see the other person less harshly, even compassionately; and, most importantly, we will come away more closely bonded with the Lord.
I might say: for your sake, Lord, I let it go. But it is really for my sake, with your assistance. Help me to decide what is needed for my peace of heart!
