How do we know God calls His people by name?

The phrase 'I have called thee by thy name' found in Isaiah 43:1 illustrates the intimacy of God's relationship with His elect. This declaration reveals not only God's foreknowledge and sovereignty but also His love and purpose for individuals. Before creation, God chose a people for Himself and made a covenant to save them. This calling is effectual and personal, demonstrating that believers are not just a part of a crowd but are specifically known and loved by God, calling them out from among the nations.
