Daniel resolved that he would not defile himself. (DANIEL 1: 8)
In addition to an overall commitment to pursue holiness in every area of life, I find it helpful to make specific commitments in areas where we’re particularly vulnerable to sin. There’s great value in identifying those areas — either in what we do (for example, gossip) or in what we fail to do (such as loving our wives as Christ loved the church) — and then making specific commitments of obedience to God in those areas.
I urge you to list any areas of temptation wherein you need to make this specific commitment. Do you need to make a covenant with your eyes about what you look at (Job 31: 1), or with your mouth about what you say, or with your mind about what you think? Is there a particular temptation or sinful practice that arises in your work environment that needs a commitment to fortify you against it? Write these commitments down on paper, for your eyes only, so you can review them and pray over them daily.
Perhaps there’s a particular area in your marriage or in your relationship with your children, your parents, a friend, or an associate at work where you aren’t demonstrating the Spirit’s fruit of love, patience, or kindness. Do you need to make a commitment that, in dependence on the Holy Spirit to enable you, you’ll seek to display that particular “fruit” toward that individual? If so, I urge you to make such a commitment. You may find the need to make several commitments — sins to put off or avoid and Christlike traits to put on. If you don’t commit yourself to the pursuit of holiness in these specific areas of your life, you’ll find a tendency to vacillate in the face of these temptations.
