Widely attributed to Lincoln, this appears to be derived from Thomas Carlyle's general comment below, but there are similar quotes about Lincoln in his biographies.
Adversity is sometimes hard upon a man; but for one man who can stand prosperity, there are a hundred that will stand adversity.
Thomas Carlyle (1841) On Heroes and Hero Worship.
Any man can stand adversity — only a great man can stand prosperity.
Horatio Alger (1883), Abraham Lincoln: The Backwoods Boy; or, How a Young Rail-Splitter became President
Most people can bear adversity; but if you wish to know what a man really is give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never used it except on the side of mercy.
Robert G. Ingersoll (1883), Unity: Freedom, Fellowship and Character in Religion, Volume 11, Number 3, The Exchange Table, True Greatness Exemplified in Abraham Lincoln, by Robert G. Ingersoll (excerpt), Quote Page 55, Column 1 and 2, Chicago, Illinois. ( Google Books Full View https://books.google.com/books?id=JUIrAAAAYAAJ&q=%22man+really%22#v=snippet&)
If you want to discover just what there is in a man — give him power.
Francis Trevelyan Miller (1910), Portrait Life of Lincoln: Life of Abraham Lincoln, the Greatest American
Any man can handle adversity. If you truly want to test a man's character, give him power.

1840s, Heroes and Hero-Worship (1840), The Hero as Priest
Context: There have been other Priests perhaps equally notable, in calmer times, for doing faithfully the office of a Leader of Worship; bringing down, by faithful heroism in that kind, a light from Heaven into the daily life of their people; leading them forward, as under God's guidance, in the way wherein they were to go. But when this same way was a rough one, of battle, confusion and danger, the spiritual Captain, who led through that, becomes, especially to us who live under the fruit of his leading, more notable than any other.
