Romans 10:9-10

Amplified Bible, Classic Edition

⁹ Because if you acknowledge and confess with your lips that Jesus is Lord and in your heart believe (adhere to, trust in, and rely on the truth) that God raised Him from the dead, you will be saved.

¹⁰ For with the heart a person believes (adheres to, trusts in, and relies on Christ) and so is justified (declared righteous, acceptable to God), and with the mouth he confesses (declares openly and speaks out freely his faith) and confirms [his] salvation.
