Of course the basic starting point in dealing with sin in our lives is to make sure we are Christians. Jesus said in Mark 7 that it is “out of the heart comes evil thoughts, sexual immorality, theft, murder” and so on. In other words, the problem is not what we wear or whether we have a tattoo or not, but our hearts, our very selves. We need new hearts, we need to be converted, we need to be born again. That is the first step.
Secondly, we need to be disciplined. Job said, “I have made a covenant with my eyes; how then could I gaze at a virgin.” (Job 31:1) Job did not presume he would automatically or magically grow in godliness, but made a covenant with himself to work on his holiness. The apostle Paul said, “I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified”. (1 Corinthians 9:27)
