We ought to repent of our sins. It good that we repent of known sins particularly and generally. I have repented of all known sins in my life. It is the repentance of grace and peace. We should rest our hopes on Christ alone. It is through Him alone we should pray through. Here are a few quotes on repentance:
Repentance is as much a mark of a Christian, as faith is. A very little sin, as the world calls it, is a very great sin to a true Christian.
C.H. Spurgeon
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
When the hand of faith opens to lay hold of Christ, it drops the sin it had grasped before. You must part with your sin – or Christ.
J. A. James
The Christian Professor.
Repentance is the hand releasing those filthy objects it had previously clung to so tenaciously. Faith is extending an empty hand to God to receive His gift of grace. Repentance is a godly sorrow for sin. Faith is receiving a sinner's Saviour. Repentance is revulsion of the filth and pollution of sin. Faith is a seeking of cleansing therefrom. Repentance is the sinner covering his mouth and crying, “Unclean, unclean!” Faith is the leper coming to Christ and saying, “Lord, if You will, You can make me clean.”
