Is Speaking in Tongues For Us Today?
No. Tongues was a sign to the unbelieving Jews (1 Cor 14:22). The Jews seek a sign where as the Gentile seeks wisdom:
"For the Jews require a sign, and the Greeks seek after wisdom" - 1 Corinthians 1:22
According to the Lord Jesus tongues are a sign - Mark 16:16-20
In the old Testament the Jews lived by signs - (Deu. 11:18; Jos. 4:6; 1 Sam. 10:7; 2 Kgs. 19:29; Isa. 7:14; 38:7, 22; Ezk. 4:3; 20:12, 20)
Also, scripture states tongues will cease (1 Corinthians 13:8).
So being tongues was a sign and being the Jews and not Gentiles seek a sign, tongues was for a sign to the Jews only.
