In Genesis 4, we have recorded the sad story of the children of Adam and Eve. Cain brings an offering to God that is unacceptable. We don’t know every detail about his offering, but it is clear that God rejected it. This story is about an unheeded warning. The Bible says that Cain was troubled that his offering had not been accepted by God. He was so troubled that it affected his countenance. God tells Cain at the outset that if he will only correct his offering, he will be gladly accepted and all will be well. On the flip side, God warns Cain that he had better get on top of this immediately.

 If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him. (Genesis 4:7)

The warning is this. Take care of the entrance of sin immediately because it lies at the door waiting to pounce on you. A rendering of the phrase, “sin lieth at the door,” gives the picture of a wild beast crouching just before pouncing on its helpless victim. 

There are moments when a sinful thought, temptation, or a wrong attitude fleets across our minds. We all face these types of things. The warning for Cain, as it is for us, is that you must deal with it immediately or it will deal with you. God was telling Cain that sin desired to have him, dominate him, and control him but that he could do something about it right now. Do not underestimate sin’s power. Do not tolerate sin in your life. Don’t rationalize it. Don’t minimize it. Don’t blame others for it. Don’t make peace with it. Do not secretly harbor it. Psalm 66:18 says, “If I regard iniquity in my heart, the Lord will not hear me.”  Ask God to keep you sensitive to any sin that creeps into your life. The Psalmist prayed that God would search him and reveal anything that was not pleasing to Him. God did just that for Cain, but he did not heed the warning.

We dare not give sin an inch. Anything not pleasing to God must be confessed, not coddled, repented of, and not regarded. What’s behind your door today? What subtle thought or attitude is present that God has softly revealed to you that it is wrong? Deal with it today…because sin is crouching at your door.
