You can know you are saved by confessing with your mouth and believing in your heart that Christ was raised from the dead.
The assurance of one's salvation is foundationally connected to the acknowledgment of Jesus Christ as Lord and believing in His resurrection, as stated in Romans 10:9-10. The act of confessing with one’s mouth signifies agreement with God's truth about who Jesus is, while believing in the heart reflects trust in His completed work. If you can affirm that you rely solely on Christ for your righteousness and have a genuine desire to know Him, these are strong indicators of being saved. Furthermore, this understanding shifts focus away from subjective feelings or experiences to objective truth in the Gospel, bringing a solid foundation for assurance.
