If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. (Romans 10:9-10, NIV)
The above prayer is just an example there are no magic words. Salvation is by grace through faith. There’s nothing you did, or ever can do, to deserve it. Salvation is a free gift from God. All you have to do is receive it!
