Here is hopefully a more succinct way of asking this question:
Do you love God because of what he is or how he behaves?
Imagine the love of a spouse or a friend. At first you love them because of how they behave, but gradually you learn to love them for who they are, not because of their behavior but despite it. Ultimately, God willing, you reach a level of friendship where you love them unconditionally.
Applying this to God, at first you are drawn to God because of his behavior. You desire his promise of salvation and want his love. Eventually, however, you must move beyond that and realize that God deserves your worship not because of what he does but because of what he is: namely, The Creator. At this point you realize that you will do literally anything for God, even burn in Hell for all eternity if that is his will. Salvation becomes unnecessary since it's your love of God that sustains you, not his promise to you. Your love for God ceases to be transactional and becomes pure.
Bringing this back to the OP, if there is anything you can imagine that God can do that will stop you from loving him then you have discovered your line in the sand. Perhaps God damns innocents to Hell? That's your line. Perhaps he chooses those he will save before Creation began and allows untold billions to wallow in misery and death. If the notion of that offends you then that's your line, etc.
I can't express this idea any clearer than this.
"WE love God because He first loved us"......1 John 4:19
The bottom line is that we should love Him for who He is and not only love Him more just when He does something for us. We should love God….JUST BECAUSE OF WHO HE IS! That’s it! No other reasons are necessary. This is a very hard concept to follow because we don’t always understand why God allows things to happen in our lives.
And that brother is where you are coming from in your questions. When I was a little boy, I did not understand why my father whipped me. I did not understand why my mother made me lie under the bed as punishment. Now I know!
They were trying to make me into a better person, a man that could see and know right from wrong. But I was just like YOU and every other little boy. I knew my parents were the Two dumbest people in the world! Now I know they were the smartest!
This principle that I have adopted into my life has not come easy…it’s been through years of going through many trials and God teaching me that He will never leave me or forsake me. I’ve gone through years of God teaching me His long-suffering techniques under the direction of the Holy Spirit. I know that getting upset with God does nothing but hurt my relationship with Him.
Just like my earthly father, I love God…because I know He has my best interest at heart and His motives are pure and perfect. I love God because He has forgiven me and He’s made me His very own child. I love God because of all the grace and mercy He sends me every single day. I love God because of the relationship that I have developed with Him resulting from our constant interaction with each other.
I love God because He sent His only Son to come down here to rescue me because I would have been lost forever. I love God because He will change me into a glorified being and He will never let me suffer anything ever again and He’s prepared a place for me to spend all of eternity.
These are reasons why I love God that has been has been growing in my heart over many years but the main reason that has developed in me is to love and worship God is because of who He is…He is God. As humans…love grows and develops within us….but when it comes to God…we should be very secure on knowing who we are in Christ and who God is to us and in us. This is revealed to us in the bible and by the Holy Spirit.
What He did with Abraham or Noah or Moses or the Israelites means nothing to me. It is what He has done for ME!
