The ability to speak in unknown languages was essential during feast days in Jerusalem when people from all over the known world gathered. It served as a sign not of divine favor, but rather as a judgment for unbelievers (see Isa. 28, 1 Cor. 14:22). It acted as a selective test to distinguish humble, receptive individuals from the "scornful" ones who refused to listen. As described in 1 Cor. 14 and illustrated in Acts 2, the mockers—those who were thoroughly unbelieving—accused the speakers of being drunk or insane. In contrast, those with open hearts sought a deeper understanding and soon heard the clear prophetic message that would convince, convert, and save them.
What about today? While we no longer possess the spiritual gift to speak in unknown tongues, some have used their knowledge of languages, acquired through study, to share the truth in foreign lands.
As time passed and generations advanced, the need for such miraculous gifts faded. The Gospel had spread throughout the known world, and from then on, the focus shifted to nurturing the love of Christ in the hearts of believers.
We live in the days of men's hearts falling them for fear so they seek for signs and wonders.
@David in NJ are you such a believer?
