Ummm...NO! We do NOT agree. There is only one God who has revealed Himself through first the Written Word and then the Word made flesh. The God of Muslims, Hindus, etc is NOT the true God who has revealed Himself because they deny His Truth. And those who deny Him are those who are leaning on their own understanding - their own concept of "god", but deny the True God.
I am curious though...since you say we cannot show what is true, why do you say your way is the only way?
As I said before: I can't. Nobody can. Neither can you. Everyone is either putting their trust in God says is Truth, or in what man says he thinks/believes is true. That isn't "my way", it is His way and He Himself says it is the only way. If it had been up to me, I probably would have done something different, would have believed something different, something that elevated me at least a little in His sight, something that I could say that at least I brought something to the table, something to have a little bit of pride in that I was able to please God. It is a pride issues. It always has been, it always will be.
I also cannot give a good concrete reason for why I am in love with my husband of almost 26 yrs as much now as I was a few short weeks after meeting him. I cannot say why I fell in love with him and knew he was the man I was to marry. And he, nor our love for each other is not God! God's ways are far above our ways and His thoughts are far above ours. We mock Him if we try to bring Him down to our level. That is when we really aren't leaning/trusting on Him, but in man/ourselves. I am sorry that you don't understand that. I truly am. Our kids now are asking from time to time when you know if they have the person they will spend the rest of their lives with. My answer to them is the same to you: When you know... you know. And you know with a certainty that you cannot explain. You know with your whole being. No doubts.
You obviously have chosen for the moment at least to believe in a way other than what He has revealed. And it is also obvious that you have had this explained to you many time. If you truly don't understand, I can't help you there, but He can. That is part of what makes Him God. If you simply resist understanding, I can't help you there either and it would be useless to keep on trying.
How would you prove, that what you accept as the written word of God, really is?
I believe as you do, that it is not up to me. It is the way God made me. God has given us different understandings.
