1) If you don't speak in tongues, How do you know if you are baptised in the Holy Ghost?Confused.
The Holy Ghost above all else is a testator of Christ. I don't believe anyone can genuinely proclaim Christ to be the savior unless they gained that knowledge from the Spirit. But the Holy Ghost is also a purifier. Through it, one becomes a new creature in Christ, moving from a carnal, sinful state to a purified, righteous one. The Book of Mormon prophet Alma described it as a "Mighty Change." And this is what comes to those who have gained the Spirit. Tongues prove nothing. The notion that one must speak in tongues if they get the spirit is not scriptural.
2)The Bible does say ALL believer shall speak in tongues...STOP TELLING LIES.
Jesus said it. Mk 16: 17.
Paul believed it. 1 Cor 14: 5. & 18, & 23 & 26.
One of the operations of tongues is, To build the believer up. 1 Cor 14: 4,
Do you think that God is a respecter of people and only gives some the tongues to build them up, But not to others???...WAKE UP.
Again, you are grossly misinterpreting what it means for God not to be a respector of persons. You seem to think that this means everyone is equal, and everyone has the same gifts, when the Bible clearly says otherwise. Read 1st Corinthians chapter twelve, pretty much the whole thing. Paul goes into detail about the essentials of spiritual gifts, likening them to parts of the body that work together for a similar goal. God doesn't give all gifts to everyone, but he expects us to use the gifts he did give us for the building up of His kingdom.
Do you think that God only wants some people to have tongues so their Spirit can pray.
1 Cor 14: 14-15??, And not others??.WAKE UP..
You don't need to speak in tongues to pray. The Spirit is perfectly capable of communicating its message in your own language. As for your other part, yes, God gave "Some" the gift of tongues. Look at 1st Corinthians 12:10
In every Biblical account where people were baptised in the Holy Ghost, They spoke in tongues...THE BIBLE RESTS IT'S CASE.
Paul didn't.
I think it's interesting that you feel tongues are the proof of the presence of the Spirit. Whenever you get the time, you should look up early LDS history. The church was full of people speaking in tongues. At the dedication of the Kirtland Temple, the church experienced its own kind of "Day of Pentecost." People spoke in tongues, prophecied, worked miracles, etc. There were many leaders who spoke in tongues as you've described it. Brigham Young himself did. So even if you disregard my experiences, are you prepared, according to your own logic, to accept that the early Mormons did possess the Spirit?
1)Again I will ask you, If you don't speak in tongues, How do you know you are baptised in the Holy Ghost???, As it is the Biblical evidence.
Every time people in the Bible were baptised in the Holy Ghost, They spoke in tongues, Proving that tongues is the Biblical evidence of the baptism in the Holy Ghost.
Jesus did say the believer shall speak in tongues, Meaning ALL believers.
One of the operations of tongues it to build us up. 1 Cor 14: 4.
ARE you saying that God only want's some Christians to have this gift to build them up, And not for other to have it,??. If so, You are saying that God is a respecter of people, And that makes Him a sinner.
So what you are saying is, GOD IS A SINNER..
The gifts in 1Cor 12, Have nothing to do with our everyday, Spiritual tongue which we use in prayer.
Everyone has at least one of the gifts in 1 Cor 12. At least they should seek after them.
They are towards our profeting.
But then we have the tongue the buld us up.
We have the tongue that is our Spirit praying.
If it wasn't needed, Why would God give it to us?

. WAKE UP.
Paul said I will pray with me understanding and with me spirit, [Tongues], And that is God's will for all His people.
2)The tongues in 1 Cor 12: 10, Are a different kind of tongue, PLEASE NOTE v10,
"Divers kinds of tongues".. See v28, "Diversities of tongues",
PLEASE NOTE, These are only one of the eight operations of tongues, They are tongues that go with the interpretation, V10, U& v28, PLEASE KEEP THE BIBLE IN IT'S RIGHT CONTEXT.
3)The lds who spoke in tongues and did miracles, were used by the devil, Because God will never confirm the mormon church, Or give them the gifts of the Spirit.
