One of the Songs at the wedding was "In Christ Alone" by Keith Getty & Stuart Townend. What a fantastic worship song it is. For a start: what a great title! It's rare to find a modern chorus with a depth of theology to match the old hymns, but if there are any contenders around today -- this must be one of them. I love it.
As we sang it, I was struck in particular by the last verse...
No guilt in life no fear in death
This is the power of Christ in me
From life’s first cry to final breath
Jesus commands my destiny
No power of hell no scheme of man
Can ever pluck me from His hand
Till he returns or calls me home
Here in the power of Christ I’ll stand!
