What does it mean for God to call His people by name?

When God calls His people by name, it indicates His intimate knowledge and commitment to them, as exemplified in Isaiah 43:1 where He assures His people that they belong to Him. This personal calling reflects God's grace, indicating that He selects, redeems, and maintains a relationship with His chosen ones. It teaches us about the security we have in Him, knowing our names are recorded in the Lamb's Book of Life. This relationship is not based on our merit but on God's sovereign choice, which brings us comfort and assurance of His everlasting love.
