1. "Christianity.com" is NOT the views of many christians. Certainly not mine, at least. The Bible is the go-to for Christianity, not christianity.com.
My church and all the others I know share the idea that the possible answers are yes, no, and wait.
2. Saying that yes, no, and wait are the only answers to prayer is stupid. Sure, if you pray for $1000, then those are the only possible answers. But what about if you pray for God to resolve a certain situation? His answer could be to resolve it in any number of ways, one of those being not resolving it at all.
My church and all the others I know share the idea that the possible answers are yes, no, and wait. What other answers might there be, since you said there were and failed to list some? As for resolving a situation, he could resolve it now, resolve it later, or not resolve it at all.
3. A freaking jug of milk hasn't been credited for making cancers disappear, tumors shrink, and any number of miracles. The people who have had these miracles done to them don't bow down and worship a jug of milk, they praise God for it. Wonder why that is?
Because people know praying to a jug of milk is stupid, they just haven't realized that praying to a God is too. The answers you get are the same, and both "answers" to prayers are all coincidences.
