But Sarah could not wait. She seems to have fixed ten years as the period during which she would wait; but at the expiry of this term she considered herself justified in helping forward God's tardy providence by steps of her own. One cannot severely blame her. When our hearts are set upon some definite blessing, things seem to move too slowly and we can scarcely refrain from urging them on without too scrupulously enquiring into the character of our methods. We are willing to wait for a certain time, but beyond that we must take the matter into our own hand. This incident shows, what all life shows, that whatever be the boon you seek, you do yourself an injury if you cease to seek it in the best possible form and manner, and decline upon some lower thing which you can secure by some easy stratagem of your own. The device suggested by Sarah was so common that the wonder is that it had not long before been tried. Jealousy or instinctive reluctance may have prevented her from putting it in force. She might no doubt have understood that God, always working out His purposes in consistency with all that is most honourable and pure in human conduct, requires of no one to swerve a hair's breadth from the highest ideal of what a human life should be, and that just in proportion as we seek the best gifts and the most upright and pure path to them does God find it easy to bless us. But in her case it was difficult to continue in this belief; and at length she resolved to adopt the easy and obvious means of obtaining an heir. It was unbelieving and foolish, but not more so than our adoption of practices common in our day and in our business which we know are not the best, but which we nevertheless make use of to obtain our ends because the most righteous means possible do not seem workable in our circumstances. Are you not conscious that you have sometimes used a means of effecting your purpose, which you would shrink from using habitually, but which you do not scruple to use to tide you over a difficulty, an extraordinary device for an extraordinary emergency, a Hagar brought in for a season to serve a purpose, not a Sarah accepted from God and cherished as an eternal helpmeet. It is against this we are here warned. From a Hagar can at the best spring only an Ishmael, while in order to obtain the blessing God intends we must betake ourselves to God's barren-looking means.
