There is no logic in Calvinism, It is the raving of a mad man named John Calvin. I follow no man, but only the Word of God.
I wasn't aware that you thought Calvinism was an invention of John Calvin. Calvinism is part of the Reformed doctrine which is calvinistic in that we believe God's word reveals to us that he is sovereign over all things, including man's salvation. The Reformed doctrine came about by the study of many, many biblical scholars who came together to determine what it actually was which God's word said since the Roman church obscured this by having it's members not able to understand the word preached since it was given in a language not understood by the people.
I'm no biblical scholar. I don't have the mental capacity to study the original languages and then take years to dissect the Bible to determine what it says. That's why we have teachers who are to explain these things to us. If we go at it by ourselves, we can come up with dozens of interpretations each of us came up with individually. Sure we can trust that a spirit is guiding us, but are we sure that it is the Holy Spirit? And it might be, since the only necessary doctrine of salvation is that Jesus Christ died for sinners by dying as a sacrifice on the cross. That's it. The rest is gray area, though some seems to be a darker almost black than others.
Personally I don't know how anyone can maintain an active, full faith without the reformed doctrine. But then that's me. I can't judge anyone else's heart, only God can do that. My understanding is that the doctrines tell us about Jesus, what we are to understand about him. I've tried reading the Bible under a non-reformed pastor and believed I did have faith at one time. In a short while I fell away from that and turned to the world and atheism. It made more sense. Years later the Lord led me to study the Westminster Confessions of Faith and for the first time I met Jesus in God's revealed word.
Is that the correct interpretation of the Bible? I fervently believe there can only be one correct interpretation and I do believe the reformed doctrine is the one, but I'd have to point you to biblical scholars for proof of that. Like I said, I'm no biblical scholar and struggle to remember verses, which ones say which. I trust in Jesus, in his finished work on the cross, and not my understanding of doctrines. We aren't given, thank the Lord, a doctrinal exam after we die.
The Lord has granted me a growing faith, an active one which ebbs and flows but that I trust he will finish the work he has begun--and I believe he has done this through the secondary means of my understanding of the reformed doctrine. I think, and I may be wrong, that if I had come to an understanding different from the reformed one I would have fallen away again like I did the last time I thought I knew and believed upon Jesus.
I will give you this though, my husband who first converted into the charismatic denomination, decided to learn the original languages and study the Bible in depth for some years and he came away with the understanding of the reformed doctrine. Me, I will trust biblical scholars that have had years of studying the Bible and knowledge of the original language before my own weak grasp of something so complex as biblical doctrine. That's just the trust for doctrine however, and like I said it is Jesus whom my faith rests upon.
The contention between brethren in Christ I do not care for, however and try to stay away from arguments. If we start saying there are other ways to God besides Jesus or that the Bible is not the word of God, then we've got a problem--that's a different God we worship then. Yet, if someone wants to believe God is not entirely sovereign or have rock-band music in church, then okay--I think it's definitely wrong but let's put these differences aside and praise the Lord Jesus for taking away our sins. Let us sing praises to glorify the blessed mercy of God! We don't have to and should not compromise on our doctrinal beliefs, but let us not strive against and contend against each other. That is the devil amongst us. Rather we should enjoy a sweet harmony and fellowship together with the Lord Jesus.
That is all I've come to say since I went to sleep last night and will put forth no more arguments. I wish all the best in our Lord Jesus Christ.
