You would be repenting of anything that goes against what pleases God, basically for not trying to live a righteous life. Yes there is pleasure in sin, I had my fair share of it aswell. But it is very true when the bible says, " that the pleasures of sin are for but a season". What is the point of living a sinful life? Sleeping around and possibly getting diseased, drinking and smoking and drugs to destroy your body and cut your life short, being selfish and inconsiderate to others. None of that lasts man. None of it is ever enough, you get bored with it and look to do more and more until you reach the point of a crack addict or alcoholic that lost everything and wonders " how did it get this far?" You told me once that you were involved with church, you never made mention of being filled with the Spirit. To be filled with God is true satisfaction. To live a life where you put others first, to do a good deed and see someone break into tears because of your kindness. To be remembered as someone that loved and lived for Jesus, who served others, who did good, who loved all, who you couldn't say anything bad about; that is a great way to be remembered, to leave behind a legacy. Or you could be remembered as the guy that knew how to have a good time but never really did anything in life, that is a man that is soon forgotten. I had my share of living for every pleasure and living the fun sinful life. It left me empty and searching for more. When I started living for God I was fulfilled and every day held something new and amazing for me.
