Paul was not writing of tongues in chapter one but repeating the necessity of believers to utter the truth of the gospel in every part of their life.
1 Cor 1:1 ¶ Paul, called to be an apostle of Jesus Christ through the will of God, and Sosthenes our brother,
2 Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours:
3 Grace be unto you, and peace, from God our Father, and from the Lord Jesus Christ.
4 I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ;
5 That in every thing ye are enriched by him, in all utterance, and in all knowledge;
6 Even as the testimony of Christ was confirmed in you:
7 So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:
8 Who shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.
9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord.
This is a call to sanctification while we await the return of Christ. To be witnesses and a living testimony for Christ.
For the cause of Christ
