GENESIS 4: 7 (NRSV)
 "...If you do well, will you not be accepted? And if you do not do well, sin is lurking at the door; its desire is for you, but you must master it."
Are you the Master? Or are you being Mastered? I have bad habits and am prone to sin, because I am human, and I am normal. But I was really struck by this passage, which lead me to realize sin is always lurking, wanting you to fall into behavior that will leave you feeling guilty, less worthy, and disconnected from God. But that is not God's intention for us. He wants us to take control, master temptations, and draw close to Him. Sin will always be there, but so is our ability to master it.
