Isaiah 35:10

And the ransomed of the Lord, those whom the Messiah has delivered from the natural slavery of sin and from the consequent condemnation of death, shall return and come to Zion with songs and everlasting joy upon their heads, this joy being visible in their entire aspect, especially in the appearance of their faces; they shall obtain joy and gladness, and sorrow and sighing shall flee away; for the Christian religion is the most cheerful religion, the absolute religion also for this reason, that it alone announces to sinners the full and free love of God in Christ Jesus. In this manner these two Chapter s are in the fullest sense of the word Messianic prophecies, finding their application wherever the kingdom of Christ is established. Cf Philippians 4:4.
