If you pour a glass of Guinness Stout, you will see some very dark beer. Blacker than Black. If poured properly you will have a nice, thin layer of white head on top. This whiteness is pure as snow in comparison to the depths of the darkness below.
How is this like the Christian life?
Our lives are dark and stained with sin.
In faith in Christ, when God the Father looks down at us, He does not see the darkness of our lives. The darkness that demands his wrath. Instead, He sees the cleanliness in the pure whiteness of the righteousness of his Son, Jesus, that covers us and justifies us as being in a right relationship with God.
This simple analogy has left out any long and detailed explanations of sin and the effects of sin. It has assumed that everyone understands that Jesus is God and that the Father is God, and that there is another person in the nature of God, and he is the Holy Spirit. These three persons are distinctly different, but still there is only one God. Now I’m probably confusing matters worse to state this, but I also didn’t give a definition for righteousness or explain how a loving God has to punish sinners, because he is also just and holy. I didn’t explain or prove any of this from the Bible, science, philosophy, or logic. This analogy simply states that our lives are dark and deep with evil, wholly depraved, but that nonetheless, the depths of our depravity are covered and made clean through the perfect life and work of Jesus. That’s why I can say that . . .
The Christian Life is like a Draft of Guinness Stout!
