The breath is God’s gift of the Holy Spirit. It is given to whomever asks for it and to say “ah” is to say please or to ask. To exhale is to ask for the Holy Spirit. When you breathe you are meditating. If you focus on what makes your breath change (holding, constricting, inhaling or exhaling) you know what is going on between you and your soul. If your soul is happy you may sigh relief. If you have lost your peace your breath may be constricted. That is your soul telling you that you are sinning.
The only unforgiveable sin in the bible is the blasphemy against the Spirit which is to die and not breathe. Jesus said in Mark 3:29 (NIV), “but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.” Once you are dead you can no longer be forgiven. Then it’s not your problem anymore because the dead know nothing. Ecclesiastes 9:5 (NIV) says, “For the living know that they will die, but the dead know nothing; they have no further reward, and even their name is forgotten.”
If you keep breathing however and there is breath in your lungs, you can ask for forgiveness and it will be granted and you will continue to breathe.
Your soul or Jesus is kind and gentle and desires that you repent and turn back to it.
