It's important to preach like there's a broken heart on every pew. That's always been a phrase that stuck with me. Not everybody is having a tough time, but you can bet your buck that there's a good tenth of your church that's going through a hard season. There really is a broken heart on every pew.
Heartache is good. Accept it joyously. Allow it, don't repress it. The natural tendency of the mind is to repress anything that is painful. By repressing it you will destroy something that is growing. The heart is meant to be broken. It's purpose is to melt into tears and evaporate. When the heart has evaporated exactly in the same place where the heart was, you come to know the deeper heart.
Though we may feel we are "like a broken vessel," as the Psalmist says (Psalms 31:12), we must remember, that vessel is in the hands of the divine potter. Broken minds can be healed just the way broken bones and broken hearts are healed. While God is at work making those repairs, the rest of us can help by being merciful, nonjudgmental, and kind.
