You’ve probably heard and told a few “Knock! Knock!” jokes over the years. In Scripture, God makes it very clear to us, just as he did to Cain, that we need to be aware of who or what is at our door.
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 [master] it.” – Genesis 4:6-7
After the fall of man, God didn’t just pick up and walk away from us. God has wanted, and will always want, us to choose to be in an intimate relationship with Him, to trust Him and obey His Word. Our God wants us to know the depth of the love, acceptance and peace that comes to us when we choose to live in a right and intimate relationship with Him.
The Lord asks us to examine ourselves and our motives so that we will not let any sin or any of our emotions – anger, hurt, fear, stress, arrogance, sadness, self-pity, self-sufficiency – rule over us more than our God. The Lord speaks warnings to us to tell us that sin is crouching at our door (Knock! Knock!). That sin desires to have us. To devour us and destroy us. And that is no joking matter. The Lord tells us that we must master sin. In saying this, God reminds us and empowers us with the knowledge that we always have a choice when it comes to sin. And I am absolutely convinced that our Lord never asks us to do anything for which He will not also equip us to accomplish it.
Sadly, you and I all choose sin, one way or another, with varying consequences for ourselves and for others. No matter what our sin is – sin always devours and always destroys. In this fallen world, sin will always be crouching at each of our doors. This isn’t a surprise.
So, how do we master sin? How do we avoid being devoured and destroyed by sin?
First, we have to want to master sin. We have to be willing to depend on God as our Lord, and not on ourselves. And certainly, we cannot allow our emotions, our knee-jerk reactions, our self-focused sense of justice and our life-warping habits to rule us. Then, we need to choose to master sin. We need to run into the loving arms of our Lord Jesus Christ – who has fully mastered the power of sin and its deadly destruction over us for all eternity. We must go Knock, Knocking on our Lord’s door for protection, self-control and the strength we need to be able to master the onslaught of temptation and the destruction of sin. Our God promises to open His door to us.
“…knock and the door will be opened to you” – Matthew 7:7
Our God has lovingly and powerfully given us all we need to master sin as we stay in His care and live in obedience to His Word. Let’s each choose to knock on our Lord’s door, instead of being knocked over by sin! It’s our choice. Knock! Knock!
