I'm not understanding how speaking in tongues builds up ones faith (edifies them.) I know a verse says it, I just don't understand how it is.
1. As you pointed out, the word of God states it, and God cannot lie.
1Co 14:4 He that speaketh in an unknown tongue edifieth himself; ...
2. The person speaking, and any human hearers do not know what is being said because it is not being spoken to them. Tongues is something being spoken to GOD, not men. ... as is stated in the very first clarifying verse about tongues in 1 Corinthians 14.
1Corinthians 14:2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him;... (I left off the last section of the verse so it could be highlighted, not disregarded, in the next point.
3. 1Co 14:2(b) " ...howbeit in the spirit he speaketh mysteries. " What is being said is hidden. but Romans 8:27(part a) Shows that God (the intended hearer) knows exactly what is being said...Rom 8:27 "And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God. "
4. Notice that the last half of Romans 8:27 is in total agreement with what is being said in 1 Corinthians 14:16-17 that prayer in the spirit, though still a mystery to others, is verily(truly) giving thanks well. 1Corinthians 14:16&17 "Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? For thou verily givest thanks well, but the other is not edified."
5. Another reason prayer in the spirit (tongues) edifies us has to do with the nature of what is being prayed...as defined in Romans 8:26 (there are actually several really good points being made in this verse). Rom 8:26 "Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered."
5a. "helpeth our infirmities" = works to overcome our weaknesses
5b. "we know not what we should pray for" = our fleshly minds just don't know what actually needs prayed, no matter how smart or godly we think we are.
5c. "the spirit itself maketh intercession for us" = That's what speaking in tongues IS, the spirit praying FOR us ...because...
5d. "which cannot be uttered." = we (using our natural mind and language) cannot speak them because of 5b. "we know not what we should pray for". God simply made (through the Spirit) a way around this particular infirmity/obstacle.
It's a super smart solution using something that (at first) appears to make no sense.
I'd love to talk more on this but gotta get ready to leave.
Love in Jesus,
