28 And God has placed in the church first of all apostles, second prophets, third teachers, then miracles, then gifts of healing, of helping, of guidance, and of different kinds of tongues. 29 Are all apostles? Are all prophets? Are all teachers? Do all work miracles? 30 Do all have gifts of healing? Do all speak in tongues? Do all interpret? 31 Now eagerly desire the greater gifts.-1 Corinthians 12:28-30
According to the Scriptures, not all speak in tongues, especially since we have now the complete Word of God. God can still use someone to speak in tongues to minister in a particular situation.
Tongues mean a known language, one that is spoken from the earth not angelic (Acts 2:4-8). God uses tongues for declaring His Word through a believer who does not speak the language of the person God wants him to minister to.
We all as believers in Christ Jesus have different gifts, we do not possess all of them. If a church tells you that you need to speak in tongues, for the evidence of the Holy Spirit, friend, they are in error and do not understand the Scriptures. If you attend a church that teaches that, I would suggest looking for a church that is more faithful to the Word of God and its interpretation.
