You'll get answers all over the board on this but I encourage you to find the balance in this. I have submitted to God through Christ over 22 years ago, my life and the life of my family is centered on Him and His ways. We're not perfect, but He is the foundation of all we do. I have never spoken in tongues, not once. Early on this really bothered me because, living on the eastern edge of central Kentucky, we border a lot of more pentecostalish churches and this is a common and popular doctrine... that the manifestation of the holy Spirit is the speaking in tongues.
As I have learned and grown, however, I realize that this is a teaching is not as sound as it's adherents believe it is. God CAN manifest Himself in the lives of believers in the form of tongues, but it is but ONE gift that is such a manifestation, and it is the least of all gifts. Consider...
1 Cor. 12:28 And God has appointed these in the church: first apostles, second prophets, third teachers, after that miracles, then gifts of healings, helps, administrations, varieties of tongues. (29) Are all apostles? Are all prophets? Are all teachers? Are all workers of miracles? (30) Do all have gifts of healings? Do all speak with tongues? Do all interpret?
The obvious answer to each question is "No," that how God manifests Himself in each of our lives is going to be different based on our callings. And yet, for some reason (I have an idea why, but won't bore you with it) tongues is taken from the bottom of the list (by a minority of Christians by the way) and exalted to the top of the list along with a non-Scriptural decree that states ALL MUST HAVE this gift. It simply isn't Scripture.
Remember, the word tongue simply means language. When the disciples spoke in other tongues in Acts 2 to the crowd below... they were speaking in OTHER LANGUAGES and when we take into consideration the verse that says that the crowd below was made up of people from other nations... then "other languages" means just that... not some unknown, gibberish sounding language.... but rather Persian, Etruscan, Greek, Latin, Parthian, etc. It was a miracle, no doubt... but it was a move of the Spirit to reach those there on that day. To take that and create a doctrine that says we all must have this (or a similar) ability is simply not a sound conclusion.
I will leave you with this... we are NOT known by our gifts, we are known by our fruit. But that fruit isn't our works... the fruit is the fruit of the Spirit within us. For we are nothing, and we can do nothing, without God. Therefore, we don't save souls and notch our belts and that is our fruit... our fruit is His fruit...
Gal. 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, (23) gentleness, self-control. Against such there is no law.
If somebody speaks in tongues but isn't kind, has no joy or peace, and there is no love in their words... I am to ignore that because they speak in tongues? Balance... find balance here sis.
Blessings.
