So I say, live by the Spirit, and you will not gratify the desires of the sinful nature.
Are you open to listening to what the Holy Spirit has to say? It's difficult to know when it is the Holy Spirit leading you, but there are several discernible ways. First, you are open to guidance. Second, you are ready to obey what the Holy Spirit guides you to do even if it is outside of your comfort zone. Third, you know the difference between your feelings and the promptings of the Holy Spirit. So, let the Holy Spirit guide your life.
