Yes obey the Gospel; the gospel command repent.
that
if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. Romans 10:9-10
- and with the mouth confession is made unto salvation.
Confessing Jesus as Lord is the confession of faith by which we are saved.
Confessing Jesus as LORD is how we obey the Gospel command to repent.
