And the ransomed of the LORD shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away.
All Commentaries on Isaiah 35:10 Go To Isaiah 35
John Cassian
AD 435
And in fact, if we look with the elevated gaze of our mind at the condition wherein the heavenly and supernal virtues that are truly in the kingdom of God make their home, what else should it be thought to be than perpetual and continual joy? For what belongs so much to true blessedness and so befits it as continual tranquility and everlasting joy?… “They shall receive joy and gladness; sorrow and groaning shall flee away.”
