How does one make their calling and election sure?

Making one's calling and election sure is an ongoing process that involves perseverance in faith and an active pursuit of godly qualities. In 2 Peter 1:10, believers are encouraged to give diligence to adding to their faith virtues such as goodness, knowledge, self-control, and love. This diligence reflects a response to God's grace and an acknowledgment of His work in their lives. By actively engaging in these virtues and continually focusing on Christ, believers can gain assurance of their election, recognizing that their spiritual fruits are evidence of the grace at work within them. Ultimately, this assurance stems from faith in Christ and the understanding that salvation is secure in Him alone.
