First, you do have to ask yourself if you believe in God.
But once that is established and I gather it has been, you have to take into account several mitigating factors.
#1: Your jealous quote is OT. I see you point, but he is not a jealous one in the NT, but a loving one.
#2: God gave man Free Will. and let us chart our own course. We are bound to make mistakes, and bound to hit road blocks. He cannot interfere due to His (her) Prime Directive. free Will.
#3: So when catastrophe hits, we must do what is best for ourselves and our brothers. If he were to interfere, then we would be just puppets on a string (much like the angels). Man, according to the JCI God, is alone amoung the heirachy in being able to do good as an act of free will, and bad, for the same reason.
In the end, we are being tested. We may be found wanting, but then it is Man's decision in that regard, not God's.
Your not worshipping him is just another nail in the coffin of man. But there are many reasons that man will be saved and one of the greatest just died this past week. Each man and woman has the capacity for good and evil within themselves. The end result is how many choose each.
If you choose good, then you are in your own way, praising him and doing his work. period.
