Absolutely. Believe and serve. Heaven is not the end game. God is supreme and deserves worship and is under no obligation to me at all. I am doubly indebted to him because he created me and I slapped him in the face by disobeying his law. So, I deserve death. The least I can do is serve God.
I also believe whomever God calls comes to Him - so if He called me with no benefit to me whatsoever then I would be compelled to obey.
Sorry, but i highly doubt that. You can say it now but facts are there to remaine.
Look at what Christ said - salvation through me - implying that salvation is the gift for believe
Look at the fanatic islamsits - they go for the job with the belief that they will go to heaven
Look at fabatic Jews - they believe because they, and only they are the chose once, and no one else will be saved at the end of the game
So whatever you say maybe true jsut for you, and maybe you are the one in a million, but for most believers (according to each instituion's religous manuscripts or books) - salvation in one way or another is the present for belief, and the main reason
No doubt there is a period along the growth path of a disciple where the motivation is carrot and stick. Just like what it takes to train a child to form good habits.
However, these days I would do anything for my mother out of love, even though there is not much more that she can do for me.
That is the way it is with God. Abba. Papa. Daddy.
