Do you merely and only believe ABOUT Jesus: facts about some character, like you would “believe” it was “true” according to the story of STAR WARS that Darth Vader was Luke’s father…?
Or—do you believe IN Jesus as your personal Savior, human and divine, crucified and killed for the washing away of all your personal sins, past, present and future, and resurrected on the third day?
You might think you are “believing” in Jesus, when all you really are doing is merely “knowing” the facts of the Gospel as one would know a work of fiction.
Some people never apply what Jesus did to themselves, that He died for their personal sins.
If in the past you merely have believed some facts were part of some story, but have not believed in Jesus for your personal soul’s salvation, you can do that right now.
Believe in Jesus for the forgiveness of all of your sins, and for eternal life, and for the salvation of your soul, and to be guaranteed of going to Heaven.
If you have not done this in the past, you can do it right now.
Believe in Jesus and be saved, and have assurance of your salvation.
