The human heart will seek to be known, understood, and connected with above all else. If you do not connect, the ones you care about will find someone who will.
When we can't hold back, or set boundaries, on what comes from our lips, our words are in charge-not us. But we are still responsible for those words. Our words do not come from somewhere outside of us, as if we were a ventriloquist's dummy. They are the product of our hearts. Our saying, "I didn't mean that," is probably better translated, "I didn't want you to know I thought that about you." We need to take responsibility for our words. "But I tell you that men will have to give account on the day of judgment for every careless word they have spoken" (Matt. 12:36).
The Bible is clear about two principles: (1) We always need to forgive, but (2) we don’t always achieve reconciliation. Forgiveness is something that we do in our hearts; we release someone from a debt that they owe us. We write off the person’s debt, and she no longer owes us. We no longer condemn her. She is clean. Only one party is needed for forgiveness: me. The person who owes me a debt does not have to ask my forgiveness. It is a work of grace in my heart.
Just as we leave the effects of our work behind in results, we leave the effects of our interactions with people in their hearts, minds, and souls.
