On the other hand, if you are unaware of any such sin in your life and you are, to the best of your knowledge, walking with Christ, then pray and ask the Lord to show you if you are overlooking something. Unless something comes to your attention, you can reasonably conclude that your difficulties are not due to some sin in your life. The grace of God is not a license to sin. Rather, it is a powerful motivation to please God by bearing much fruit. Believers who play with fire will get burned.
Sin is fire.
Fiery judgment awaits the unfruitful, non-abiding believer.
