Why is understanding the 'called' significant in Christianity?

The term 'the called' refers to a specific group of people whom God has chosen for salvation, as mentioned in Romans 8:28. This concept underscores that salvation is not based on human effort or merit but on God's sovereign purpose and grace. 2 Timothy 1:9 affirms that we are called not according to our works, but according to His own purpose and grace given to us in Christ Jesus. Recognizing that we are among 'the called' provides immense security, confirming that our acceptance into God's family is not contingent on our fluctuating faith or actions, but solely on His sovereign decision. This truth encourages believers to trust wholly in the efficacy of Christ's work on the cross, knowing that His calling is effectual and irreversible.
