This may be my favorite quote from the pen of Hannah More (1745–1833), the poet, reformer, and abolitionist, as published in The Works of Hannah More (New York; Harper & Bros., 1846), 1:434:

What a triumph for the humble Christian to be assured, that ‘the high and lofty One which inhabiteth eternity,’ condescends at the same time to dwell in the heart of the contrite — in his heart! To know that God is the God of his life, to know that he is even invited to take the Lord for his God. To close with God’s offers, to accept his invitations, to receive God as his portion, must surely be more pleasing to our heavenly Father, than separating our happiness from his glory.

To disconnect our interests from his goodness, is at once to detract from his perfections, and to obscure the brightness of our own hopes. The declarations of inspired writers are confirmed by the authority of the heavenly hosts. They proclaim that the glory of God and the happiness of his creatures, so far from interfering, are connected with each other. We know but of one anthem composed and sung by angels, and this most harmoniously combines ‘the glory of God in the highest with peace on earth and good will to men.’ …

This God is our God — God, even our own God, shall bless us. How delightful the appropriation! To glorify him as being in himself consummate excellence, and to love him from the feeling that this excellence is directed to our felicity! Here modesty would be ingratitude; disinterestedness rebellion.

This is a beautiful description of what we now call Christian Hedonism.
