The entire book of Romans 8 about the assurance of salvation. Every Christian wants to be assured that he is actually saved. Many people wander around “in the flesh” believing that they’re saved, but if they read this chapter, it becomes the actual measure of salvation. It is a really good chapter to read if you want the assurance that you are indeed saved. This particular verse says that those who are walking in the spirit of God are the sons of God. If we’re led by the Spirit of God, what does that mean? What Paul is trying to tell us here is that if we are walking in the spirit of God, then we are actually going to kill the sin in our lives. We’re going to want it dead in order to please God, to glorify Him. You see, people who are not in the spirit, who were still walking in the flesh don’t really want to kill their sin. People who lie don’t want to stop lying; people who gossip don’t want to stop gossiping. If they do put on some semblance of killing their sin, it’s just so they’ll look better– not because they want to please God, Paul tells us here that if we truly want to be the sons of God, the children of God, then we are going to be led by the spirit. So one assurance of our salvation is this: we ask ourselves the question, “Am I trying to kill my own sin because I want to please God?” If the answer to that question is “yes,” then you are the child of God. That is evidence that the spirit lives in You because only the spirit in You would want to put an end to the sin in Your life. If you want assurance of salvation, look within to see what your motivations are for ending your own sin.
And we pray:
Father, I thank You for giving me assurance of my salvation. I ask that You help me to examine my heart to see what my motivations are. I want to kill my own sin because I know that it pleases You. I want to stop any sin in my life because I want You to be glorified and I want to be Your child. Help me to be led by Your Spirit so that You may call me Your child. Amen.
