One Spirit!

He who is joined to the Lord, is ONE spirit together with him – 1 Cor 6:17

Powerful words written by a man who wrote more than half the bible. It’s strange to me how no one has ever taught me a single insight in regards to the truth of these words. How can it be possible to become ‘one spirit’ with the God of the living? There is no religion on earth that teaches anything like it.
