Does that mean only those who speak in tongues are redeemed?
The tongues miraculously spoken at Pentecost were identifiable human languages.
Which one has God gifted you with? Swahili? Dutch? Apache? And would you be willing to post audio of your gift?
You are stuck on that idea but the scripture does say---
1Co 14:2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
As you claim to be baptized into the body of Christ, yet know nothing of the gifts then you need to rethink your position of unbelief.
1Co 12:8 For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;
1Co 12:9 To another faith by the same Spirit; to another the gifts of healing by the same Spirit;
1Co 12:10 To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:
1Co 12:11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
1Co 12:12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
1Co 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
1Co 12:14 For the body is not one member, but many.
You claim none of those gifts, even fighting against them, yet you think you are in the body of Christ.
Do you really believe you can be baptized into the Body of Christ and have no gift given you, when the word says God gives severally as He wills?
and--
Eph 4:7 But unto every one of us is given grace according to the measure of the gift of Christ.
Eph 4:8 Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.
Eph 4:9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth?
Eph 4:10 He that descended is the same also that ascended up far above all heavens, that he might fill all things.)
Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
Eph 4:12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Eph 4:13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
