What does it mean to make your calling and election sure?

In 2 Peter 1:10, believers are encouraged to make their calling and election sure by actively seeking to follow Christ and confirm their faith through obedience and growth in godliness. This assurance does not imply that one can alter God's sovereign choices, but rather it emphasizes the importance of believing the gospel and engaging in a relationship with Christ. True assurance comes from understanding that salvation is a work of God in the believer's heart, evidenced by a desire to live in accordance with His will. Hence, making one’s calling and election sure is about resting in gospel truths and living out the implications of one's faith.
