Yes, Paul gives 16 reasons in just one letter why we should speak in tongues in the church:
1 – We are to desire the spiritual, and tongues exemplify the spiritual (1 Corinthians 14:1, 12).
2 – He that speaks in tongues speaks to God in a direct way that allows for the mysteries of God to be spoken. There would be no way for Paul to give tongues a higher status than to refer to it as the activity of our spirit speaking directly to God by the Holy Ghost (1 Corinthians 14:2).
3 – When we speak in tongues, we strengthen ourselves in the things of the Spirit (1 Corinthians 14:4).
4 – It was Paul’s desire that we all speak with tongues, and no one knew better what was needed in the church (1 Corinthians 14:5).
5 – Tongues will excel to the interpretation of tongues. Therefore, if there are no tongues then we will be deprived of a special realm of prophecy: the interpretation of tongues (1 Corinthians 14:12-13, 27).
6 – When we pray in tongues, our spirits are engaged in prayer to God (1 Corinthians 14:14).
7 – Without tongues we would not be able to pray in the Spirit, which leads to praying in the understanding (1 Corinthians 14:15).
8 – Without tongues we would not be able to sing in the Spirit, which then leads to singing in the understanding (1 Corinthians 14:15).
9 – When we speak with tongues, we bless with the Spirit (1 Corinthians 14:16).
10 – When we speak with tongues, we give thanks (1 Corinthians 14:16).
11 – When we speak with tongues, we give thanks excellently (1 Corinthians 14:17).
12 – Paul, an example that we should all follow, spoke in tongues more than everyone. (1 Corinthians 14:18)
13 – Speaking in tongues is the fulfillment of prophecy, which revealed that God would speak through His people in a special way (1 Corinthians 14:21).
14 – Speaking in tongues is a sign for the unbeliever: it is a revelation that the New Covenant has begun (1 Corinthians 14:22, Acts 2:33).
15 – When we assemble in the church, everyone should have the expression of tongues (1 Corinthians 14:26).
16 – Tongues is the first expression of the Holy Spirit in the church, and no one has the right to forbid it (1 Corinthians 14:39, Acts 2:3-4).
Jesus told us that believers would speak with new tongues (Mark 16:17). Paul’s instruction and empowerment was more extensive than just his address to the Corinthians (Acts 19:6, Colossians 3:16, Ephesians 5:17-19). The Apostles understood tongues to be proof that God had extended salvation to the Gentiles (Acts 10:44-46, 11:15-18). Jude commanded that believers pray in tongues to edify their most holy faith (Jude 1:20). God also spoke of these days in the Old Testament (Isaiah 28:11, Joel 2:28-29, Zephaniah 3:9). While tongues is not the ultimate focus and center of the faith, it has an unshakable biblical foundation – all believers should be zealous to speak with tongues and glorify God!
