"Sin is Crouching at the Door"

While reading my Bible last night (starting a new bible reading plan), I read again a passage that my pastor discussed in a recent sermon. Genesis 4:7 says, "if you do not do well, sin is crouching at the door. Its desire is for you, but you must rule over it." This was God's warning to Cain prior to the murder of Able. This seems to be simple advice, but just like the words "giving birth" cannot adequately describe the intensity of the process, so do the words "you must rule over it" mask the intense process of conquering sin. This passage, however, does encourage us to be diligent, because sin is ready for us especially when we are not. May God give us diligence in good deeds and victory in Christ!
