 See you have to repent of your sins. On the day of Pentecost Peter said, they said, what shall we do? They wanted to believe. He says, repent and be converted. And times of refreshment will come from the presence of the Lord. To repent means to turn from known sin. Now honestly you may not know all the stuff you are doing is sin yet. So you repent of what you know to repent of. And as you get to know the Lord better you repent of more things. Because you realize there are a lot of things that aren't right.
