Genesis 4:7a If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door.
Opportunity knocks, sin lays in wait.
Allow me to ask one of my pointed questions. On which side of the door is sin? Looking at the issue of not doing well as being Cain’s sin, one might say it is on the inside of the door and does not need to knock.
Revelation 3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
Nearly every commentator of bible scriptures acknowledges that the door is the door to a sinner’s heart. John 14:23 supports that idea in the abiding presence of the Father and the Son. I do not have issue with that, but it is a door, not the heart. It is an obstacle that needs to be transformed into an entrance.
Psalm 119:11 Thy word have I hid in mine heart, that I might not sin against thee.
It is error to think that just because you answered the door and let Jesus it that sin fled through the open door as Jesus entered. Not so, the Word enters in to assist us that we “might” not sin. There is no exodus of sin, only light to shine upon it so that we “might” see it for what it is.
We have been set free from the power of sin but not its presence.
1 John 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
No matter how many times I vacuum under the bed, dust bunnies reappear. Do you know why? They are made up primarily dead skin cells and light has a difficult time shining under my bed. Such is the life we lead, chasing bunnies.
