That's not what Jesus allegedly promised. It is right there in black and white. Ask for it and you will receive it.<quoted text>
If Jane prays to win the lottery is God required to let her win the
lottery? No. God will still answer her prayer, but God isn't required to answer a prayer the way we think it should be answered after all we are fallible human beings.
If there is a god, and his response to prayer is to do what he thinks best, what is the point of praying? Presumably, god is going to do what he thinks best regardless of your prayer. So, whether you pray or don't pray, the outcome will be the same either way. Prayer has no effect on the outcome. If Jane has cancer and prays for a cure, the prayer will not affect the outcome. If your god intends for her to die from cancer, then that is what will happen, prayer or no prayer. If god does not plan for her to die that way, she will be cured, prayer or no prayer. And all the promises to grant believers what they pray for? As Elwood Blues said in the Blues Brothers movie, "I took the liberty of bullsh*tting you". "It wasn't lies, it was just bullsh*t".
So, if the parts of the gospels where Jesus promises to deliver up whatever you pray for can't be believed, how can you say with any degree of confidence that any other part of the gospel isn't at least as suspect?
