Yes He gets jealous, Not of your good things, But of the things that distract you from His presence,
When God gets jealous He takes away that which you put first before Him, He gets you to know that only He should come first,
When God gets jealous, He let's you know why what you're putting above Him is useless, He takes it away, So you can realise that its only in Him that you can find total goodness,peace and security..
