It is well to bear in mind that there are certain great truths--certain immutable principles--which underlie all the dispensations of God from age to age and which remain untouched by all the failure, the folly and the sin of man. It is on these great moral truths, these foundation principles, that faith lays hold, and in them finds its strength and sustenance. Dispensations change and pass away, men prove unfaithful in their varied positions of stewardship and responsibility, but the word of the Lord endureth forever. It never fails. "Forever, O Lord, Thy word is settled in heaven." And again, "Thou hast magnified Thy word above all Thy name."[III.] Nothing can touch the eternal truth of God, and therefore what we want at all times is to give that truth its proper place in our hearts; to let it act on our conscience, form our character, and shape our way. "Thy word have I hid in my heart, that I might not sin against Thee." "Man shall not live by bread alone, but by every word that proceedeth out of the mouth of the Lord." This is true security. Here lies the real secret of decision for Christ. What God has spoken must govern us in the most absolute manner ere our path can be said to be one of plain decision. There may be tenacious adherence to our own notions, obstinate attachment to the prejudices of the age, a blind devotion to certain doctrines and practices resting on a traditionary foundation, certain opinions which we have received to hold without ever inquiring as to whether or not there be any authority whatever for such opinions in Holy Scripture. There may be all this and much more, and yet not one atom of genuine decision for Christ. Now we feel we cannot do better than furnish our readers with an example or two drawn from the page of inspired history, which will do more to illustrate and enforce our theme than aught that we could possibly advance. And first, then, let us turn to the book of Esther, and there contemplate for a few moments the instructive history of "MORDECAI THE JEW."
