One of my favorite hymns is 350 in the The Christian Science Hymnal. I find it so healing! I love affirming that 'All will be well' and then deepening that prayer to 'All must be well' and finally arriving at "All is well."
Here is Christa Seid-Graham so wonderfully humming the melody. You can go ahead and sing along. Nobody will mind. :)
Through the love of God our Saviour All will be well; Free and changeless is His favor; All must be well; Precious is the Love that healed us, Perfect is the grace that sealed us, Strong the hand stretched forth to shield us; All, all is well.
Though we pass through tribulation, All will be well; Ours is such a full salvation, All must be well; Happy still, in God confiding, Fruitful, when in Christ abiding, Holy, through the Spirit’s guiding; All, all is well.
We expect a bright tomorrow, All will be well; Faith can sing through days of sorrow, All must be well; While His truth we are applying, And upon His love relying, God is every need supplying, All, all is well.
