Summary
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth one confesses unto salvation. - Romans 10:9–10
Paul connects confession and belief: salvation comes through personal acknowledgment of Jesus’ lordship and faith in His resurrection.

Explanation
When a person confesses Jesus as Lord and believes that God raised Him from the dead, that confession marks their conversion and salvation. It is not just an affirmation of doctrine but a declaration of allegiance, recognizing Jesus’ authority and submitting to His reign.
Where Who is Jesus reveals the church’s foundation: that Jesus is the Christ, the Son of the living God, Romans 10:9–10 describes how people are joined to that Church: through faith that produces confession. The church is built on the revealed truth of who Jesus is and grows as people personally confess Him as Lord.
This confession unites believers under Christ’s authority and distinguishes the Church as a community of those who publicly identify with Him.
