On Love that is Christian
A wonderful Lewis quote from a recording of The Four Loves radio broadcast series, more or less the same as in his book with that title.
"Such, I conceive, is the world of agape. A world of unbounded giving and unchained receiving. Where all blessed creatures need, and know that they need, nothing but God, and are therefore set free to love one another disinterestedly. And so your love shall be like His; born neither of your need or of my deserving, but of plain bounty. I think those are drawing near to heaven, who, in this life, find that they need men less and love men more, and delight more in being loved without being needed. For where agape is, there is in some degree, heaven."
