uh, er, hmm.., so if one does not pray in tongues and have prophetic utterances they are not saved? I don't remember Jesus saying these were necessary. Hmm, lemme check John 3:16 again..... ...... nope, they are not there............
It is true that once saved, the newborn believer must begin to fill their souls and lives with Christ. Studying Scripture, seeking Gods purpose for their lives, fellowshipping with other believers and seeking to be Sanctified.
Speaking in tongues (other languages) is a gift of the Spirit. However, there are many more. The Apostle Paul didn't consider speaking in tongues to be all that important in discussing the gifts of the Spirit. Agape love (charity) i the greatest is it not?
