Yes, it is. We cannot be saved by faith only. God asks us to have an obedient faith.
Acts 2:38, Marc 16:16 show us that baptism is necessary !

In Hebrew 11, we see that every time people had faith, they were obedient and did what God asks them to do. Faith was never alone.

Baptism is a requirement for salvation giving the great commission our Lord Jesus gave us before leaving earth. Matt. 28:19 says "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.
