Here’s a fine old 18th century hymn to pump you up–Soldiers of Christ, Arise, sung by Maddy Prior to the old, perhaps original, musical arrangement.
Again on the hymn’s youtube page I find wistful comments by atheists, who love the music but remain standing on the outside, looking in.
But you can come in! The door is open. And the good things that you see inside, more valuable than anything you could pay for them, are already yours–the free gift of God. For Jesus Christ has already paid the bill, and you are free and clear.
As are we all who gather in His presence.
