"Out of the depths have I cried unto Thee, O Lord. Lord, hear my voice: let thine ears be attentive to the voice of my supplications. If Thou, Lord, shouldest mark iniquities, O Lord, who shall stand? But there is forgiveness with Thee, that Thou mayest be feared." (Psalm 130:1-4)
Taking the heat
I have such respect for Job. His adducement of "Though He slay me yet will I trust in Him: but I will maintain mine own ways before Him." (13:15) has all the confidence of someone, I would say, who truly knows the Lord. Someone who has walked before him through bad times and worse, through thick and thin and all the points and counterpoints of their life. Of course, it was uttered in response to those who had taken their best stab at Job's problems only to find his resolve and resilience withstanding the onslaught of their wisdom and words.
"Wherefore should I fear in the days of evil, when the iniquity of my heels shall compass me about?" (Psalm 49:5)
Job continues on in the chapter by asking two things. And while the King James doesn't explicitly say he's asking and demanding of God, I can't see his request of "Only do not two things unto me" (13:20) as directed at anyone else. Because, let's face it, only God has the power to exact such things on a human being. Job asks "Withdraw thine hand far from me: and let not Thy dread make me afraid." (v. 21) Thing is, if we truly understand the character of God, how "God is love", then the thing that should cause us to fear Him, i.e. judgment is to be coupled with the experience of having been forgiven. It took the sublime pain and agony of the cross to purchase for us the inestimably important forgiveness we need to live. Then Job goes on to accuse God of libel (!) and the dredging of sins long past. "For Thou writest bitter things against me, and makest me to possess the iniquities of my youth." (v. 26) Here's the thing. As satan is "the accuser of our brethren" (Revelation 12:10), the constant worry and fear around the things we've done wrong in our past is brought about, not by God, but by the devil. If you've received forgiveness for it, move on. Sorry, that's a little blunt. Perhaps there's something more God wants to teach you, not to the condemnation of your spirit, but to the education of the same with reference to moving forward.
Taking the heat elsewhere
"God is in the midst of her (referring to the "city of God" Ps. 46:4); she shall not be moved: God shall help her and that right early. The heathen raged, the kingdoms were moved: He uttered His voice, the earth melted." (Psalm 46:5-6)
The term thermoduric pertains to organisms that are able to withstand extremely hot temperatures. A bacterium that is able to survive the pasteurization process, for instance. I read once of a type of worm that lives below the crust of the earth (granted, it's been taxonomized after the devil--Halicephalobus mephisto--bear with me a little in my analogy) that survives and thrives in temperatures above two-hundred degrees. The point I'm getting at is that because of what Jesus has done on the cross, the heat of God's anger and censure is only meant to burn off anything that would keep us from getting closer to Him. This, I think, is what God wants us to focus on should He in any way turn up the heat.
