What does it mean that the Lord knows those who trust in Him?

In Nahum 1:7, it is stated that 'the Lord knows them that trust in Him.' This knowledge goes beyond mere awareness; it signifies a deep, intimate relationship. God recognizes and understands His people, having chosen them before the foundation of the world. This relationship provides comfort in trials as believers are assured that they are not merely statistics in His creation but are cherished individuals personally known by their Creator, granting them security and confidence in His promises.
