Billy Joel has a song where he states it's my life. Leave me alone when we stop and think about it. We've been bought with a price as believers is not our life. It belongs to God if you're not a believer, your life belongs to Satan. Satan's desire is to deceive us in the believing our life can be our own.
1 Corinthians 6:19-20 CSB
[19] Don't you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, [20] for you were bought at a price. So glorify God with your body.
