Let not sin therefore reign in your mortal body, to make you obey its passions.Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness.
Romans 6:12-13 ESV
Do you understand that sin is a choice? Well for those of us in Christ it is. We have been freed from the bondage of sinful habits and desires. Why would anyone want to live in that anymore?
