Why is the concept of Christ as a sympathetic High Priest important for Christians?

In Hebrews 4:15, the assurance that we have a High Priest who is able to sympathize with our weaknesses is crucial for believers. This allows us to approach Him boldly at the throne of grace, as we know He has experienced human suffering and temptation. His ability to empathize with us stems from His real human nature, making Him not just a distant deity but a Savior deeply involved in our lives. This doctrine encourages believers to bring their needs and struggles to Christ, confident that He cares and will provide the necessary grace in times of trouble.
