Adam became a living soul when God breathed into him the breath of life: and from that time, the process of breathing is evidence that life exists. Prayer may be regarded as the breathing of the spiritual man. Sufficient proof was given that Saul of Tarsus had been converted, when the Lord said, "Behold, he prayeth." True prayer proceeds from the Holy Spirit, imparting spiritual life, and enkindling those spiritual desires which find their vent in prayer. These desires are breathed into the bosom of God, in the exercise of filial confidence in him; and, being in accordance with the will of God, they are regarded by him with favor, and obtain answers of grace and peace.
From this view of prayer, we may see the propriety of the Apostle's injunction: "Pray without ceasing." The cessation of prayer would be the cessation of spiritual life. A form of words may not be incessantly used; but spiritual desires must ever have place in the heart; and the habit must ever exist, of looking to God for the fulfilment of these desires. This constant intercourse with God is the life of faith. We live with him, converse with him, and enjoy communion with him, through the Holy Spirit which dwelleth in us.
We often complain that our prayers are not answered; but it would be profitable to inquire, what those unanswered petitions were. Did we ask for wealth, power, and long life? If so, our desires were carnal, and did not proceed from the Spirit of God. We must learn to regulate our desires by the will of God, and our prayers will be sure to obtain a gracious hearing.
Sincere prayer begins with the very commencement of spiritual life. An infant's cries express its wants, before it knows how to express them in words; and the tender mother will understand this inarticulate language. So the desires of the spiritual infant may be signified by "groanings which cannot be uttered:" but the Lord understands these groans, and knoweth what is the mind of the Spirit, who maketh intercession for them. As the lamb in the bosom of the kind shepherd; as the babe on the breast of its tender mother; so the spiritual babe reposes on the bosom of eternal love; and in that bosom breathes all its desires.
Spiritual life, evidenced at first by the breathing of prayer, is afterwards indicated by spiritual growth. To be spiritual, we must not ever remain babes in religion. Paul said to the Corinthians, "I could not speak unto you, as unto spiritual, but as unto carnal, even as unto babes in Christ." Spiritual life is progressive, and tends to make us men, strong men in Christ Jesus. The truth of God supplies the milk for babes, and the strong meat for those who have attained to greater age. We have been engaged in the study of this truth; and it will be well for us to inquire whether our spiritual life has been nourished by it, and whether we are growing in faith, and love, and every grace. Unless the truth strengthens the inner man, and gives increased vigor in the Christian life, our study of it has been in vain.  Gen. ii. 7.
