Repentance is the inseparable companion of faith. All the while that we walk by faith and not by sight, the fear of repentance glitters in the eye of faith. That is not true repentance which does not come of faith in Jesus; and that is not true faith in Jesus which is not tinctured with repentance. Faith and repentance, like the Siamese twins, are vitally joined together. Faith and repentance are but two spokes in the same wheel, two handles of the same plow. Repentance has been well described as a heart broken for sin and from sin, and it may equally well be spoken of as turning and returning. It is a change of mind of the most thorough and radical sort, and it is attended with sorrow for the past and a resolve of amendment in the future. Repentance of sin and faith in divine pardon are the ways and woof of the fabric of real conversion.
C.H. Spurgeon
