When we do that, it gets better and better righteousness leading to holiness. When you were slaves to sin, you were free from the control of righteousness. When we sin, it might look like we are free from outside control, but we are really enslaved. Sin produces death, and we do not want to serve that kind of master. In earlier chapters, Paul vigorously denied that our obedience causes or earns our salvation salvation is a gift, based on faith, not works.
Sin has bad results.
It gives us what we deserve. New life in Christ, on the other hand, has wonderful results, in this life and in the future. It is not a miserly payout it is a generous gift, given in advance. Choose life, Paul says.
