There is no place where sin creeps in more frequently than in the realm of affection. One does less harm by hatred than by false love. If we desire that our inward man shall grow and prosper, then let us undertake a thoroughgoing investigation of ourselves and allow our hearts to be cleansed of all impurity. Love constantly seeks the eternal in its neighbor, and it points toward this with gentleness and seriousness, and even, if necessary, with unswerving insistence. Carnal love is blind, but divine love has an open eye for truth.
Carnal love loves in order to be loved.
True love loves without expecting any gratitude. It does not consider what it can achieve for itself, but, rather, what can be produced for the Lord. It loves all the way to death, even if it is brought to the cross with the Master. Carnal love also loves unto death, yet not unto Christ's death but unto spiritual death. Wounds are received which cannot be healed through a whole long life.
