“Sin is a renouncing of Him who made me. It is refusing Him His right to govern me. It is the determination to please myself; thus, it is rebellion against the Almighty. Sin is spiritual lawlessness, and utter disregard for God’s authority. It is saying in my heart: I care not what God requires, I am going to have my own way; I care not what be God’s claim upon me, I am going to be lord over myself. Reader, do you realize that this is how you have lived?”
