How do we know Christ's sympathy for us is true?

We know Christ's sympathy is true because He willingly took on human nature and experienced life as we do. The Bible teaches that 'in that He Himself has suffered being tempted, He is able to support those who are tempted' (Hebrews 2:18). His incarnation shows that He understands our emotional and physical pain, giving us confidence that He can relate to our struggles. The fact that Jesus walked the same paths we do and faced trials offers believers assurance that their Savior is intimately aware of their challenges and fully empathetic to their needs.
