Jesus taught something "concerning the Spirit". What did He teach?
"He who believes into Me, as the Scripture has said, out of his innermost being shall flow rivers of living water." This promise is to you who read, to you who read and believe in Jesus Christ the Son of God.
God's promise "as the Scripture has said" is that the believer in Jesu ...[text shortened]... the Lord Jesus Christ to flow into you and through you according to the words of the New Testament.
All very nice html’d conjecture.
The Bible does not, ever, in any translation, use the phase “Jesus flowing through”.
Nor does it use not, ever, in any translation, the phrase “fountain of blood”
Nor does it use not, ever, in any translation, the words “trinity” or “triune”.
These are post biblical phrases and words which have been manufactured to support off centre doctrines and teachings.
