Speaking with tongues is available to be done by all Christians today. It is proof that God raised Jesus up alive from being dead and that Jesus is the Lord and the Christ. Christians can pray in spirit during our private lives by speaking with tongues to God, even though these words are a mystery to the person praying. We can also speak in a tongue and speak the interpretation of those words when we are in a gathering of the church, thereby allowing any unbelievers present to hear the sign proving that God has accomplished redemption and salvation by means of the Lord Jesus Christ whom He raised from the dead.
