St Antony the Great

Sayings of the Desert Fathers

The soul that really loves God and Christ, though it may do ten thousand righteousnesses, esteems itself as having wrought nothing, by reason of its insatiable aspiration after God. Though it should exhaust the body with fastings, with watchings, its attitude towards the virtues is as if it had not yet even begun to labour for them. - St. Macarius the Great

You shall love the LORD your God with all your heart, with all your soul, and with all your mind. (Matt 22:37)
