Believers, can you still not make up for your sins?

Sorry, but my God looks for sincerity from us. But if it would only be a matter of adding up an account that a person knowing that they could continue living in sin as long as they do a lot of good things; we would most miserably be in chaos. As for my God, He is a God of justice, therefore shall He reward the consequence to those living is willful, deliberate sin. The concept of people being allowed to sin as long as they do lots of good things is secular principles and practices, not heavenly.
