This work, The Tree
or, The Mosaic Economy a Dispensation of the Covenant of Grace, by the justly renowned Alexander Stewart of Cromarty, is considered, by those who are familiar with it, to be one of the most spiritual treatments of the Old Testament types.
Even although the volume contains but the remnants of Stewart's pulpit instruction, it shows his profound and original thinking, tempered by a reverent abiding within the bounds of Scripture. One of his hearers wrote of his preaching, "One of the most striking characteristics of Mr. Stewart's originality was the solidity of the truths which always evolved. His was not the ability of opening up new vistas, in which all was unfamiliar. . . It was, on the contrary, the greatly higher ability of enlarging, widening, and lengthening the avenues long before opened up on important truths; and, in consequence, enabling men to see new and unwonted objects in old familiar directions."
