Young Glory is inspired by a quote from puritan writer Alexander Peden,
"Grace is young glory"
The name is a reminder that the saving grace we receive through Christ will ultimately result in the glory of an eternity with God.
Or, as another puritan Thomas Watson puts it,
"The kingdom of grace is nothing but the beginning of the kingdom of glory.
The kingdom of grace is glory in the seed,
and the kingdom of glory is grace in the flower.
The kingdom of grace is glory in the daybreak,
and the kingdom of glory is grace in the full meridian...
The kingdom of grace leads to the kingdom of glory.”
