True repentance includes sorrow for sin and contrition of heart. It breaks the heart with sighs and sobs and groans...

An idle life and a holy heart is a contradiction.

Christ dwells in that heart most eminently that hath emptied itself of itself.

As heat is opposed to cold, and light to darkness, so grace is opposed to sin. Fire and water may as well agree in the same vessel, as grace and sin in the same heart.
