2. _Be watchful._ Be wakeful; be attentive and earnest――in contradistinction from the drowsy condition of the church. ¶ _Strengthen the things which remain._ The true piety that still lives and lingers among you. Whatever there was of religion among them, it was of importance to strengthen it, that the love of the Saviour might not become wholly extinct. An important duty in a low and languishing state of religion is, to “strengthen the things that still survive.” It is to cultivate all the graces which do exist; to nourish all the love of truth which may linger in the church; and to confirm, by warm exhortation, and by a reference to the gracious promises of God’s word, the few who may be endeavouring to do their duty, and who, amidst many discouragements, are aiming to be faithful to the Saviour. In the lowest state of religion in a church there may be a few, perhaps quite obscure and of humble rank, who are mourning over the desolations of Zion, and who are sighing for better times. All such it is the duty of the ministers of religion to comfort and encourage; for it is in their hearts that piety may be kept alive in the church――it is through them that it may be hoped religion may yet be revived. In the apparent hopelessness of doing much good to others, good may always be done to the cause itself by preserving and strengthening what there may be of life among those few, amidst the general desolation and death. It is much to preserve life in grain sown in a field through the long and dreary winter, when all seems to be dead――for it will burst forth, with new life and beauty, in the spring. When the body is prostrate with disease, and life just lingers, and death seems to be coming on, it is much to preserve the little strength that remains; much to keep the healthful parts from being invaded, that there may be strength yet to recover. ¶ _That are ready to die._ That seem just ready to become extinct. So, sometimes, in a plant, there seems to be but the least conceivable life remaining, and it appears that it must die. So, when we are sick, there seems to be but the feeblest glimmering of life, and it is apparently just ready to go out. So, when a fire dies away, there seems but a spark remaining, and it is just ready to become extinct. And thus, in religion in the soul――religion in a church――religion in a community――it often seems as if it were just about to go out for ever. ¶ _For I have not found thy works perfect before God._ I have not found them _complete_ or _full_. They come short of that which is required. Of what church, of what individual Christian, is not this true? Whom might not the Saviour approach with the same language? It was true, however, in a marked and eminent sense, of the church at Sardis.
