How does the concept of grace relate to the call of believers?

The concept of grace is intertwined with the call of believers, signifying that our selection for salvation is not based on our merit but rooted in God's sovereign choice. Romans 1:7 refers to believers as 'called saints,' highlighting that their status as saints and beloved is a result of God's grace. This does not merely signify a general call but implies an effectual calling where God, in His mercy, opens our hearts to believe the gospel. 1 Corinthians 1:26-31 further reinforces this by stating that God chose the weak and despised of the world to shame the strong, illustrating His grace in action. Thus, the call of believers is a powerful testament to grace, showcasing God's love and purpose.
