For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things just as we are, yet without sin. Therefore let us approach the throne of grace with confidence, so that we may receive mercy and find grace for help at the time of our need. Hebrews 4:15-16 NASB

Our Great Shepherd knows every hurt and every bruise His sheep endure, because He Himself has suffered greatly. He is therefore able to sympathize deeply with us.
