Sometimes an old hymn is just what we need to lift up our hearts and souls. So many of the old hymns are laced with Scripture, and singing them speaks much deeper to our hearts than we know. (God’s word always goes much deeper than we know.) Here is a beautiful rendition of O God, Our Help in Ages Past (with subtitles so you can sing along!).
The reason why singing is such a splendid shield against the fiery darts of the devil is that it greatly helps us to forget him, and he cannot endure being forgotten. He likes us to be occupied with him, what he is doing (our temptations), with his victories (our falls), with anything but our glorious Lord. So sing. Never be afraid of singing too much. We are much more likely to sing too little. (Amy Carmichael)
