Before you read any further, yes I’m aware of Genesis 2:7, but consider this…
God the Father is a spirit. He’s a life-giving spirit. He is life.
John 4:24 (KJV)
God is a Spirit: and they that worship him must worship him in spirit and in truth
1 Corinthians 15:45 (NKJV)
And so it is written, “The first man Adam became a living being.”[a] The last Adam became a life-giving spirit.
Romans 8:11 (NKJV)
11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
If God breathed, that would mean He would have to have His life sustained. He sustains life.
It would mean He had lungs which, would mean could die.
He can’t die…He won’t die…and if we accept Yeshua Jesus Christ we won’t SEE death either.
John 8:51 (NKJV)
51 Most assuredly, I say to you, if anyone keeps My word he shall never see death.”
Oh yeah…I know what you may be thinking. what about Him ‘breathing’ the breath of life into Adam? It doesn’t mean He literally placed His ‘mouth’ over Adam’s nose and exhaled. God is presented anthropomorphically (ascribing human attributes to something or a being that’s not human) often in the bible. He’s a spirit…no hands, feet or even a heart. God doesn’t need a ‘brain’ to have thoughts. He just simply presents Himself that way in His word to help us understand how He interacts with us and the natural world.
Speaking of the natural world, think about it…Plants produce oxygen and absorb carbon dioxide, but they don’t inhale or exhale. God uses them to produce the life sustaining oxygen that our mortal bodies need to survive.
God doesn’t have to inhale or exhale to ‘breathe’ life.
Even His word is ‘God-breathed’ inspiration (2 Timothy 3:16), that isn’t literally exhaled from holy lungs, but spiritually inspired directly from the ‘mind’ of God (1 Corinthians 2:16).
Does God have to breathe? I don’t think so…God is breath.
