God is jealous FOR us, not jealous "of" us.
He's not vigilant in guarding Himself and creation so that we can't know Him or have Him. No!
He is vigilant in guarding US who are His creation, His Beloved, made in His image and likeness by Christ, His prize, that we might believe how jealous He is for us, and have Him (God) as our inheritance by faith, not works. Yes! Amen!
