Just as there is a process that leads to immorality, there is also a process that leads away from it toward a godly lifestyle. The first step of the process back to God is to make the relationship with Christ number one in importance in your life. The decision is not to stop immorality, but to follow Him.
Decide now to commit to Jesus---or decide not to. If you claim to belong to Him, decide to make that relationship a priority. If you don't want to do that, stop claiming that you belong to Him and stop further degrading His name by your behavior.
Jesus said, "He who is not with me is against me....." (Matthew 12:30). When you say that you are with Christ, you are making a commitment to make your relationship with the living God the number one priority in your life.
The difference between this commitment to Christ and any you may have made in the past is that this time you are putting your relationship with Him in the forefront of your awareness. The first time your commitment may have been to gain eternal life. But with this commitment you are saying to the Lord of all you say, think and do....the Lord of your life.
If He is first, then relationships with others will only be fulfilling if they are ones He would approve of. If Christ is Lord of your life, there will be a power present to begin the process of turning from situations that are ungodly. When you decide to establish ( or re-establish) a relationship with Christ, you have taken the first step in the process back to godliness.
