Thus, if we want to become inwardly strong, we must learn more and more to recognize Christ's love.
We must learn to recognize its "width" that it is wider than the whole world; it embraces all sinners and, indeed, everything that lives in heaven and on earth.
We learn to recognize its "length" that this love is longer than the duration of the world; it is from eternity and extends until eternity.
We must learn to recognize its "height" for this love is higher than all the mountains of the world; it reaches even to heaven.
We must learn to recognize its "depth" for this love is deeper than the foundation of the earth; it is a deep, inexhaustible, unfathomable spring that flows from the depths of God's own heart.
