Then the Lord said to Cain, “Why are you angry? Why is your face downcast? If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”
It is an interesting thing God says to Cain here. It proves the nature of man that sin is always there. It also says that sin is always at our doorstep. It shows that sin is ready to pounce on us and destroy us. But also it shows that there is a two part thing for us to do. We must be obedient to God at this moment and be free of sin. While the text does not specify exactly why the Lord rejected his offering, but what is interesting is that it had to do with the matters of the heart. The hidden sin we have directly affects our relationship with God. Our relationship with God is dependent on our obedience and our attitude towards Him and His laws. Here there was something suspicious about Cain, and then sin took over him.
Our nature is crazy, but it seems that if we do not keep ourselves in check then we are prone to sin. Here the lesson is that God will provide, but we got to make the effort. We have to be better at staying away from sin. It is like the verse from James, “Submit yourselves, then to God. Resist the devil, and he will free from you.” We have to resist the devil, but the only way to do that is to submit to God. Because sin is right there ready for me to stumble in.
Lord thank you for the warning. I want to submit to You.
