You must pray with all your might. That does not mean saying your prayers, or sitting gazing about in church or chapel with eyes wide open while someone else says them for you. It means fervent, effectual, untiring wrestling with God. This kind of prayer be sure the devil and the world and your own indolent, unbelieving nature will oppose. They will pour water on this flame."
I know divers, and divers men know me, which love me as I do them: yet if I should pray them, when I meet them in the street openly, they would abhor me; but if I pray them where they be appointed to meet me secretly, they will hear me and accept my request.
The spirit of prayer is a pressing forth of the soul out of this earthly life, it is a stretching with all its desire after the life of God, it is a leaving, as far as it can, all its own spirit, to receive a spirit from above, to be one life, one love, one spirit with Christ in God.
The spirit of prayer is for all times and occasions; it is a lamp that is to be always burning, a light to be ever shining: everything calls for it; everything is to be done in it and governed by it, because it is and means and wills nothing else but the totality of the soul - not doing this or that, but wholly given up to God to be where and what and how He pleases.
