This is an endless debate! Have U ever answered an altar call at a church that preaches: "if U dont speak in tongues, U are not saved"? This pill may be difficult to swallow. When a preacher lays hands on U & everything transfigures, while they "try" to cause 'slain in the Spirit' for not satisfying their need of a sign, look at them. U will see snakes biting them. Those who are bitten are not truly in the spirit. They will jump to their feet & say Hallelu(Yah), begin babbling & fall on the ground, but these are those who will deny the prophecies. For they do not understand the spiritual gifts (1 Corinthians 12), & having no discernment, do not test the spirits or know the tongue they speak. In spirit, tongue means language. There are NO language barriers for The Spirit of God (Acts 2). Only those with the spirit of babylon will babble as though it were the tower or babel all over again!
