Do you believe (as the Pentecostals and Evangelicals) that speaking in tongues can get you closer to God?

Please explain this one to me.

From the wikipedia article here

‘Speaking in tongues’ is given various meanings by various people that are dependent on their viewpoint. Those who consider the outward appearance of the phenomenon understand ‘speaking in tongues’ to be the glossolalia practised by some Christians; that is, it consists of utterances that approximate words and speech, rather than being words and speech. Others, usually Christians themselves, dispute that understanding of the practice and therefore dispute the meaning of ‘speaking in tongues’; they may assert that when people ‘speak in tongues’ they “speak in languages which they have not learned”[4] (xenoglossia), perhaps the language of angels.[5] Among such, what is spoken is understood to be a ‘message from God’,[6][7][8] although some limit it to “prayer or praise”.[9]

Is gibberish the language of the angels?
