Late one night while on the road, touring, Steve Curtis Chapman called his wife to say hello. He could hear their fourth child crying in the background. He knew that his wife was tired and that she would not get too much sleep that night. He wanted to let her know that she mattered and that what she was doing to care for their children was changing the world -- one heartbeat at a time. He wanted her to know how much he appreciated her and wanting to encourage her, he wrote this beautiful song that is so inspiring and perfect for Mother's Day.
