With the establishment of Christianity on Pentecost 33 C.E. that would involve not just Jews locally but also "devout Jews from every nation under heaven" (Acts 2:5), there was now a need for extraordinary measures, such as speaking in different "tongues", in making known "the good news of the Kingdom......to all the nations".(Matt 24:14; see Acts 1:8)
The need thus arose for "speaking in different languages"(Acts 2:4), for without this extraordinary measure caused by God, many who were there in Jerusalem for this occasion, though a Jew, would not be as able to understand "the magnificent things of God" as readily (Acts 2:11), that was now being proclaimed in "his own native language", due to coming from such distant places as Rome, Italy, Elam located on the Persian Gulf or southern Iraq to the island of Crete to Libya in north Africa to Arabia.(Acts 2:8-11)
The apostle Paul realized that after Jesus established the Christian congregation in 33 C.E., that it was like a child that required considerable help to become established, using "spiritual gifts", such as "different tongues"(1 Cor 12:28) to carry it along until it became "grown".(1 Cor 12:1)
So, at 1 Corinthians 13, he stressed the necessity of showing love that exceeded the value of the other "gifts", saying: "If I speak in the tongues of men and of angels but do not have love, I have become a clanging gong or a clashing cymbal. And if I have the gift of prophecy and understand all the sacred secrets and all knowledge, and if I have all the faith to move mountains, but do not have love, I am nothing. And if I give all my belongings to feed others, and If I hand over my body so that I may boast, but do not have love, I do not benefit at all".(1 Cor 13:1-3)
Paul establishes that agape love will always remain while the extraordinary "spiritual gifts", such as speaking in tongues" will cease, saying: "Love never fails. But if there are gifts of prophecy, they will be done away with; if there are tongues, they will cease; if there is (supernatural) knowledge, it will be done away with".(1 Cor 13:8)
Paul now illustrates this: "When I was a child, I used to speak as a child, to think as a child, to reason as a child; but now that I have become a man, I have done away with the traits of a child".(1 Cor 13:11) Thence, when the Christian congregation reached ' becoming a man ' from being a child, it no longer required the miraculous "spiritual gifts" to support it.
In our day, the Christian congregation is now grown, without the need for the extraordinary help from our Maker, Jehovah God, as in the 1st century. In these "last days" (2 Tim 3:1), the Christian congregation is full grown in grasping what the Bible really teaches and using modern technology and its capabilities, it can handle the monumental task of seeing that the people of the some 6,800 languages and dialects around the earth can have "the good news of the Kingdom" printed and taught in their mother tongue before ' the end comes '.(see Matt 24:14)
So, there is no longer any need for the miraculous "speaking in tongues", that day having passed away in the 1st century, but love will always remain.(1 Cor 13:13)
