Jill Briscoe, author of It Had to Be a Monday, discusses eight things that ruin our joy and what we can do to deal with them in Heartstrings. Like the Israelites by the river of Babylon, Christians are often tempted to hang their harps in the trees and stop singing God's songs of joy. Through a discussion of eight types of those trees, such as the Grudge Tree and the Gloom Tree, Heartstrings helps those struggling in their spiritual lives by using stories from the Bible and contemporary lives to overcome these obstacles. Question sections assist readers, in groups and individually, throughout the book.
