I think that the thing that strikes me about Tozer is that his fifty year old writings are so applicable in our present day. How my heart beats with his in the desire and priority of Christ focus.
. . . Only engrossment with God can maintain perpetual spiritual enthusiasm because only God can supply everlasting novelty. In God every moment is new and nothing ever gets old. Of things religious we may become tired; even prayer may weary us; but God never. He can show a new aspect of His glory to us each day for all the days of eternity and still we shall have but begun to explore the depths of the riches of His infinite being
If we offer converts something beside Christ or something in addition to Christ we should not be disappointed if they do not run well or long. Novelty soon wears off everything, no matter how precious. When the interest begins to flag we try to recapture it by fiery exhortations. I for one admit that I am weary of the familiar religious pep talk. I am tired of being whipped into line, of being urged to work harder, to pray more, to give more generously, when the speaker does not show me Christ. This is sure to lead to a point of diminishing return and leave us exhausted and a little bored with it all. And from there we may easily grow backwards and become smaller and less fervent than when we were first converted.
I have spent many uncomfortable hours in prayer meetings listening to my brethren begging for blessings, but all prayer is comfortable when the heart is having fellowship with God and the inner eyes are looking upon His blessed face. I have suffered through many a dull and tedious sermon, but no sermon is poor or long when the preacher is showing me the beauty of Jesus. A sight of His face will inspire love and zeal and a longing to grow in grace and in the knowledge of God. . .
