If it were as simple as you say, there would be no forums. There are many factors at work. For example, Psalm 37: says that if we will delight ourselves in the Lord, He will give us the desires of our hearts. What it means is that God will actually place within our hearts His desires. Some would believe from just a simple reading that He would give the individual's current desires.
So scripture must be understood often by intent, and even through revelation. It's not necessarily apparent from simply reading.
And you actually are being rude if someone asks for a particular manner of response and you do it in the manner you choose. Not that I've taken offense, but love actually defers to the other person.
I am sorry you found my unwillingness to state what I believe to be rude. However, it has been my experience that those who ask for a yes or no answer have an ulterior motive for doing so. Giving a direct answer usually results in a personal attack.
I do my best to stay focused on what is or is not found in the word in an attempt to avoid stifling a productive discussion. As unfortunately people have biases that bring conversation to a screeching halt. And as I'm sure you know, hindering the word from going forth is a tactic of the enemy. For when God's word goes forth it will not return void; it brings forth life.
"For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:
So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it." Isa 55:10-11
However, since I don't want to be labeled rude, here goes. I'll see if my past experience holds true:
You asked, "Is it your contention that anyone who has never spoken in tongues is not saved?"
So there is no confusion by others reading my comment. First, I will reiterate what I shared from scripture. No one can be saved without being indwelt by the Holy Spirit. (Rom. 8:9) And tongues was the sign that the indwelling had taken place in regards to all individuals. The same experience is detailed in 3 separate conversion accounts. (Acts 2:4, 33, 10:44-45, 19:5) And is alluded to in this Thread.
In addition, I was given insight, earlier today, concerning the topic. In Luke 11:13, Jesus said to ask for the Holy Spirit if you have not received the gift. God's provision of a sign allows a person to know without a doubt whether or not they have received the Holy Spirit.
I am aware of no other sign that proves the experience. And therefore since I believe the word of God, my answer is, Yes.
