well i think you have to realise the meaning behind how its said.
i think he does keep his promises and makes promises for a reason, like amy said.
and he created and was obligated to take care of us to an extent too, like suzannah said.
but i think there is meaning it in some ways of thinking and application, but many people get angry at God when he doesnt please them, people say God should do this and that when he doesnt have to do anything more than what hes already done, and things like that.
also, people kinda think they can come to God and say "YOU OWE ME!" and think they can demand of God in a "you have to serve me" kind of way.
God answers prayers through our faith and love and righteousness, not becuase we can say to him "YOU BETTER KEEP YOUR WORD OR IM GOING TO ACCUSE YOU OF LYING! YOU BETTER!"
but when people think they a have an extra card up their sleeve and will be able to throw it out and kinda win the game agaisnt God...hehe...no .
God keeps his word, but he is King and no one can say unto his creator 'why have you made me this way?" and the bible says we must come to the Lord and fall down upon our faces before our creator...thats not a "you owe me" attitude. God isnt told what to do by anyone.
the moment you step into pride and think your something in yourself and God owes you because of who you are, you sin and God doesnt have to give you anything.
if we say "God owes me" out of the feeling that you dont like being treated a certain way and would hate for God to put you through a certain experience and try to negotiate out of it becuase we are better than that...thats pride, and no he doesnt owe us in that sense.
he doesnt answer prayers becuase he owes us, he answers prayers becuase hes a father and loves us.
in 1 peter the bible says husbands can have their prayers hindered, if they dont love their wives. God wont just answer anyones prayers, you have to love him and serve him and walk according to his will and please him.
the bible says also in proverbs or psalms one, that to the perverse, he will show himself perverse (that not a quote).
if you come to God with a perverted way of thinking and demanding, he will not heed you, and hell let you think hes a very perverse God.
the bible says God resists the proud...
you can come to God in prayer, and ask of him, but he will press you aside and resist you, if you have pride in you.
the bible says he resists evil doers,the bible says hes does not hear sinners.
those are several occasions where God wont answer your prayers, no matter how he created you and is supposed to watch out for you, or how often he said hed answer your prayers.
i dont think we can come with the mindset that we will receive becuase he owes us, because people think the reason he owes us is because of US... becuase we are full of ourselves, and thats pride, and he resists pride, thats the first of seven things he absolutely hates.
ya know what im saying?
