Then you've got the wrong prescription. :) Who says prayers are not of consequence? Not us. That they do not change God's mind does not mean they are meaningless. God ordains that we pray. The Bible tells us that God already knows everything that we need and even everything that we are going to say in prayer. Does the Bible then imply that they are a waste of time? Of course not. Prayers glorify God and are beneficial to us in the communication. For example, the more I pray the more I am reminded of my utter dependence on Him. From that my love for Him develops and grows. This is regardless of whether the subject of the prayer is granted.
I’ll bite. What is salvation now and what is salvation then? How do they differ? They must differ because you point them out separately.
In the way I am speaking of it, these are milestones in time. Principally, one can correctly talk about salvation "happening" when Christ died on the cross for the sins of the elect. Or, one could also correctly speak of salvation as being at the point of belief. Likewise, one could refer to the actual entry into Heaven. These are three different events in time, but are inextricably tied together for the elect. No single one can happen without the other two necessarily happening. It's all three or none of them. The Bible also uses the word "salvation" in three tenses, and this is an explanation.
Why does God ordain that we pray?
How is God glorified by the Reformed praying to Him? If He is responsible for everything that we do or say, does that mean that you are the mirror for God to look into?
Are you further saying that prayer is for your benefit because you understand better your dependence on Him, and because of that your love for Him grows? Is this orthodox Calvinism?
Further; are you saying that nobody can believe in God if Jesus didn’t die? Is this also orthodox Calvinism?
