We try to salve our nagging conscience by some minor exercise of repentance, which is really no repentance at all. The whole heart is changed in the believer. You may repent so generally that you never repent of any specific sin at all. The man who repents in too great a generality is likely covering his sins. If there are no particular changes, there is no repenting.
Sin has many heads, like the mythological Hydra.
It cannot be dealt with in general, but its heads must be cut off one by one. You may repent for the love of friends and religious leaders and not repent for the love of God. A man talked into repentance may reform for the love of friends or the respect of the spiritually minded, yet do nothing substantial. If a man turns from sin without turning to God, he will find his sin has only changed its name and is hidden behind his pride. Now it will be harder to rout for its subterfuge.
