How do we know God knows our name?

The assurance that God knows His people by name is a profound truth found in Isaiah 43:1, where God says, 'I have called thee by thy name; thou art mine.' This relationship signifies that God has a personal engagement with each believer, affirming their value and identity in Him. Further narratives, such as the account of Lazarus in the New Testament, illustrate that when God calls individuals, they respond to His voice. God's omniscience encompasses not just knowing names but knowing believers deeply, as He has chosen them before the foundation of the world, which is a testament to His sovereign grace and love.
