We share the greatest source of all, SCRIPTURE!
The message of salvation is so clear it seems foolish to the unsaved.
John 3:18 He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
Understanding all the finer points is where the complexity is found, but not in the message of salvation. It always goes back to one thing, FAITH in JESUS our LORD and SAVIOUR.
AMEN, brother! :)
