2 Peter 1:10-12

For this reason, beloved ones, be eager to confirm and validate that God has invited you to salvation and claimed you as his own. If you do these things, you will never stumble. As a result, the kingdom’s gates will open wide to you as God choreographs your triumphant entrance into the eternal kingdom of our Lord and Savior, Jesus the Messiah. I won’t hesitate to continually remind you of these truths, even though you are aware of them and are well established in the present measure of truth you have already embraced.
