How do we know God knows our sorrows?

We know God understands our sorrows through various avenues. First, through His omniscience, He is fully aware of our situations, as nothing escapes His notice. Secondly, God knows our afflictions personally; in Christ, He experienced the full weight of sorrow and suffering. As our sympathizing High Priest, He partakes in our sufferings (Hebrews 4:15), ensuring that when we face trials, we do not do so alone. His presence and understanding provide a profound comfort, reminding us that He is intimately involved with our lives and cares deeply for our hearts.
