I’ve gone back to this song a lot since our daughter died in December. The Piper soliloquoy in the middle of the song is life-changing.
Don’t say, “it’s meaningless!” It’s not. It’s working for you an eternal weight of glory. Therefore do not lose heart, but take these truths and day by day focus on them. Preach them to yourself every morning. Get alone with God and preach his word into your mind until your heart sings with confidence that you are new and cared for.
