How can we understand the concept of being 'called' in the context of salvation?

In the context of salvation, the term 'called' signifies God's sovereign initiative in drawing His people to Himself. Romans 10 recounts that not all who hear the gospel obey and believe, which points to the effectual nature of God's calling, distinguishing between a general call to all and a specific, saving call to the elect. This calling is rooted in the grace and mercy of God, who chooses to reveal Himself to those whom He has predestined for salvation. Thus, understanding this calling encourages believers in their assurance of salvation and reinforces the sovereign grace theme throughout Scripture.
