Francois Fenelon's Spiritual Progress: Instructions in the Divine Life of the Soul, Chapter 15, On The Presence of God

The presence of God calms the soul, and gives it quiet and repose even during the day, and in the midst of occupation — but we must be given up to God without reserve. When we have once found God, we have nothing to seek among men; we must make the sacrifice of our dearest friendships; the best of friends has entered into our hearts, that jealous Bridegroom who requires the whole of it for himself.

It takes no great time to love God, to be refreshed by his presence, to elevate our hearts to Him, or to worship Him in the depths of our soul, to offer to Him all we do and all we suffer; this is the true kingdom of God within us, which cannot be disturbed.

When the distraction of the senses and the vivacity of the imagination hinder the soul from a sweet and peaceful state of recollection, we should at least be calm as to the state of the will: in that case, the will to be recollected is a sufficient state of recollection for the time being. We must return toward God, and do everything which He would have us do with a right intention.

We must endeavor to awake within ourselves, from time to time, the desire of being devoted to God in all the extent of our powers; in our intellect, to know him and think on him, and in our will, to love him. We must desire too, that our outward senses may be consecrated to him in all their operations.

Happy is he whose mind contains only what is necessary, and who thinks of nothing except when it is time to think of it! so that it is God who excites the impression, by calling us to perform his will as soon as it is exhibited, rather than the mind laboriously foreseeing and seeking it. In short, let us be accustomed to recollect ourselves during the day and in the midst of our occupations, by a simple view of God.  Let us separate ourselves from all that does not come from God. Let us utter no useless word.

While outwardly busy, let us be more occupied with God than with everything else. To be rightly engaged, we must be in his presence and employed for  Him. At the sight of the Majesty of God, our interior ought to become calm and remain tranquil. Once a single word of the Saviour suddenly calmed a furiously agitated sea: one look of his at us, and of ours toward Him, ought always to perform the same miracle within us.

We must often raise our hearts to God. He will purify, enlighten, and direct them. Such was the daily practice of the sacred Psalmist: "I have set the Lord always before me." (Psalm 16:8) Let us often employ the beautiful words of the same holy prophet,  "Whom have I in heaven but thee? And there is none upon earth that I desire beside thee! God is the strength of my heart and my portion forever!" (Psalm 73:25-26)
