What does the Bible say about calling and election?

In 2 Peter 1:10-11, the Apostle Peter encourages believers to give diligence to make their calling and election sure. This means that believers are to earnestly seek confirmation of their salvation and relationship with God. The assurance of our calling and election is foundational to our faith; it underpins our confidence as we await our place in the everlasting kingdom of God. Peter emphasizes that if we are diligent in these pursuits, we will not fall but instead will be abundantly welcomed into Christ's eternal kingdom, reflecting the security found in God's grace.
