Serious dealing with God in prayer is wrought in us by the Spirit, in whose light we see both God and ourselves, his majesty and our vileness, his purity and our sinfulness, his greatness and our nothingness.
Do not waste time bothering whether you “love” your neighbor; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone you will presently come to love him.
It is a greater glory to us that we are allowed to serve God, than it is to him that we offer him that service. He is not rendered happy by us; but we are made happy by him. He can do without such earthly servants; but we cannot do without such a heavenly Master.
