“Little deeds of kindness,
Little words of love,
Make our pleasant earth below
Like the heaven above.”

Song 28: "For the Lord's Day Evening".
1710s, Divine Songs Attempted in the Easy Language of Children (1715)

Canto III, stanza 2.
The Lay of the Last Minstrel (1805)
Context: In peace, Love tunes the shepherd's reed;
In war, he mounts the warrior's steed;
In halls, in gay attire is seen;
In hamlets, dances on the green.
Love rules the court, the camp, the grove,
And men below, and saints above;
For love is heaven, and heaven is love.

Opening lines, Ch. 1, "The River Bank"

Context: The Mole had been working very hard all the morning, spring-cleaning his little home. First with brooms, then with dusters; then on ladders and steps and chairs, with a brush and a pail of whitewash; till he had dust in his throat and eyes, and splashes of whitewash all over his black fur, and an aching back and weary arms. Spring was moving in the air above and in the earth below and around him, penetrating even his dark and lowly little house with its spirit of divine discontent and longing.

Book of Taliesin (c. 1275?), The Elegy of the Thousand Sons
Context: The number that have been, and will be,
Above heaven, below heaven, how many there are.
And as many as have believed in revelation,
Believed through the will of the Lord.
As many as are on wrath through the circles,
Have mercy, God, on thy kindred.
May I be meek, the turbulent Ruler,
May I not endure, before I am without motion.
Grievously complaineth every lost one,
Hastily claimeth every needy one.

"Little Things" in the Myrtle (1845). This poem came to be published uncredited as a children's rhyme and hymn in many 19th century magazines and books, sometimes becoming variously attributed to Ebenezer Cobham Brewer, Daniel Clement Colesworthy, and Frances S. Osgood, but the earliest publications of it clearly are those of Carney, according to Our Woman Workers: Biographical Sketches of Women Eminent in the Universalist Church for Literary, Philanthropic and Christian Work (1881) by E. R. Hanson, as well as Familiar Quotations 9th edition (1906) edited by John Bartlett, The Oxford Dictionary of Quotations (1999) by Elizabeth Knowles and Angela Partington, and The Yale Book of Quotations (2006), ed. Fred R. Shapiro.

Fruits of Solitude (1682), Part I
Context: Love is indeed Heaven upon Earth; since Heaven above would not be Heaven without it: For where there is not Love; there is Fear: But perfect Love casts out Fear. And yet we naturally fear most to offend what we most Love. What we Love, we'll Hear; what we Love, we'll Trust; and what we Love, we'll serve, ay, and suffer for too. If you love me says our Blessed Redeemer) keep my Commandments. Why? Why then he'll Love us; then we shall be his Friends; then he'll send us the Comforter; then whatsover we ask, we shall receive; and then where he is we shall be also, and that for ever. Behold the Fruits of Love; the Power, Vertue, Benefit and Beauty of Love! Love is above all; and when it prevails in us all, we shall all be Lovely, and in Love with God and one with another.
