It fortifies my soul to know <br />That, though I perish, Truth is so: <br />That, howsoe'er I stray and range, <br />Whate'er I do, Thou dost not change. <br />I steadier step when I recall <br />That, if I slip, Thou dost not fall.<br /><br />Arthur Hugh Clough<br /><br />http://www.poemhunter.com/poem/with-whom-is-no-variableness-neither-shadow-of-t/
