We all desire immediate and direct answers to our prayers, and are tempted to become discouraged when the answer is delayed or comes in an unlooked-for form. But God is too wise and good to answer our prayers always at just the time and in just the manner we desire. He will do more and better for us than to accomplish all our wishes. And because we can trust His wisdom and love, we should not ask Him to concede to our will, but should seek to enter into and accomplish His purpose. Our desires and interests should be lost in His will. These experiences that test faith are for our benefit. By them it is made manifest whether our faith is true and sincere, resting on the word of God alone, or whether depending on circumstances, it is uncertain and changeable. Faith is strengthened by exercise. We must let patience have its perfect work, remembering that there are precious promises in the Scriptures for those who wait upon the Lord.
