Where is it in the Bible that someone must “remember” an event in order for God to confer His grace? Your God is very small.
Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
Romans 10:13- For whosoever shall call upon the name of the Lord shall be saved.
if you must believe in your heart on Jesus and in his death burial and resurrection and you must according the bible- then you will remember it if you do it, nobody can give salvation to another person, Jesus died for all people but its every individual persons choice to call on him for salvation. he gives us free will because he desires our hearts and our worship. its not about saying words percectly its about acknowledging our sin nature and our need for salvation.
