I apologize for the delayed response! And thanks for the compliments. I'm enjoying the several conversations I'm engaged with on here more and more. It's encouraging in its own way.
This is fair. I would say it's more, though. Like Indiana Jones, Raiders of the Lost Ark, more. Christ shows us the Father in a way which can actually have meaning for us, yes. For outside the Word, God is incomprehensible to us. But he also rescues us from God's wrath. Without Christ, without God's work and promise, our relationship with him is that between rebellious creatures and their justly wrathful creator (think "sinners in the hands of an angry god"). The exceedingly good news is that, for Christ's sake, God has promised himself to be a God of mercy and love. (Jn. 3:16ff.)
I can understand why it is less than a pleasant theological assertion, this jealous God. But if he is the one who created all things, governs all things, is merciful and loving, etc., then when humanity is busy making false gods of themselves and praying to empty idols or denying God's existence, even we can admit (hypothetically) he has every right to be jealous; he's not getting what is owed him. What exactly it means for the Almighty to be "jealous" isn't perfectly clear; it's an anthropomorphism. But it fits. It tells us he wants us as his own. It tells us we are guilty of provocation. It tells us that justice must be served or assuaged somehow. For Christ's sake, God's jealousy becomes his passionate desire for his children to return (thinking of the parable of the prodigal son/the two sons).
But I'd hate to travel too far from the subject of the thread! Thanks for the questions. My responses were brief. I hope you're staying warm and enjoying family.
Cordially in Christ
