Perhaps it may be the loss of some dear friend or relative through which the call comes to us; which shows us the vanity of things below, and prompts us to make God our sole stay. We through grace do so in a way we never did before; and in the course of years, when we look back on our life, we find that that sad event has brought us into a new state of faith and judgment, and that we are as though other men from what we were. We thought, before it took place, that we were serving God, and so we were in a measure; but we find that, whatever our present infirmities may be, and however far we be still from the highest state of illumination, then at least we were serving the world under the show and the belief of serving God. Or again, perhaps something occurs to force us to take a part for God or against Him. The world requires of us some sacrifice which we see we ought not to grant to it. Some tempting offer is made us; or some reproach or discredit threatened us; or we have to determine and avow what is truth and what is error. We are enabled to act as God would have us act; and we do so in much fear and perplexity. We do not see our way clearly; we do not see what is to follow from what we have done, and how it bears upon our general conduct and opinions: yet perhaps it has the most important bearings. That little deed, suddenly exacted of us, almost suddenly resolved on and executed, may be as though a gate into the second or third heaven--an entrance into a higher state of holiness, and into a truer view of things than we have hitherto taken. Or again, we get acquainted with some one whom God employs to bring before us a number of truths which were closed on us before; and we but half understand them, and but half approve of them; and yet God seems to speak in them, and Scripture to confirm them. This is a case which not unfrequently occurs, and it involves a call "to follow on to know the Lord[13]." Or again, we may be in the practice of reading Scripture carefully, and trying to serve God, and its sense may, as if suddenly, break upon us, in a way it never did before. Some thought may suggest itself to us, which is a key to a great deal in Scripture, or which suggests a great many other thoughts. A new light may be thrown on the precepts of our Lord and His Apostles. We may be able to enter into the manner of life of the early Christians, as recorded in Scripture, which before was hidden from us, and into the simple maxims on which Scripture bases it. We may be led to understand that it is very different from the life which men live now. Now knowledge is a call to action: an insight into the way of perfection is a call to perfection.
