1 Corinthians 12:4-10b
Jesus Christ has invested His church with self-sustaining spiritual gifts for the purpose of growth, edification, and the common good of all it’s members, and for the good of the world.
Each of these gifts is ordained in Christ’s church to provide a particular service to the Body. And every one of these Spirit ordained services produces God’s desired effects upon it’s recipients. The primary purpose of God for all His children is that we would grow without hindrance or delay.
The Holy Spirit is both the essence of, and the power behind each of the gifts.
Among the spiritual gifts Christ has invested in His church is the gift of various kinds of tongues. It is the ability to speak by the Holy Spirit in a unique way, through a language known or unknown to us today.
The gift of various languages should only be used in the assembly when there is also one gifted by the Holy Spirit to interpret the various languages being spoken.
The gift of speaking in various languages edifies the person blessed with this gift, and is most often used in prayer and worship by those who possess it.
