After you posted this, I answered in 9954.
I believe that we had a long discourse here some time ago that prayer is not supplication and we are not actually asking God for anything - it is merely worship.
I don't remember ever saying that myself. God clearly tells us to bring our requests to Him, so supplication is certainly a part of prayer, imo. I have said that it is not the ONLY thing.
Q. 178. What is prayer? A. Prayer is an offering up of our desires unto God, in the name of Christ, by the help of his Spirit; with confession of our sins, and thankful acknowledgement of his mercies.
Sounds like the Reformed are not to pray to God for help.
Why do you say that? If our desire is "help" then the Holy Spirit helps us to ask for help. All the questions you quoted are consistent. We are to ask God for help.
WCF CHAPTER 3 Of God’s Eternal Decree -- 1. God, from all eternity, did, by the most wise and holy counsel of his own will, freely, and unchangeably ordain whatsoever comes to pass:
Sounds like nothing that we do matters, since all has been ordained. Am I a little mixed up, or is the Reformed faith a tad schizophrenic?
I don't know if you're mixed up, but I do know that the Reformed faith is not schizophrenic. :) When you say nothing "matters" to us, I need to know a little more about what you mean by that. God's will being carried out within time on earth matters to God and all Christians because we all want that to happen. If nothing we do "matters" unless man has the power to thwart God's original perfect will, then I would say you are a little mixed up. :)
As I posted somewhere here today, the Larger Confession makes it abundantly clear that the Lord’s Prayer is petition - that is, asking for things.
You do not ask for things if you know that they are going to come about for sure. You only ask for things if you know that they are not going to come about. Therefore, the theology of a Creation set in stone is completely incompatible with petition.
