What are 'cannot lie' promises?

'Cannot lie' promises refer to commitments made by God that are certain to be fulfilled because He, by nature, cannot lie. These are differences from human promises, which can be broken or unfulfilled. Scripture such as 2 Corinthians 1:20 illustrates that all God's promises in Christ are 'yes' and 'amen.' This highlights that every aspect of salvation—from election to glorification—rests on God's unwavering commitment to His promises, ensuring believers can hold fast to the hope provided in eternal life and grace.
