How do we know that Jesus is our merciful High Priest?

Jesus Christ is described as our high priest who, being fully human, understands our struggles and serves as our intercessor. He bore the sins of His people, expressing His need for mercy as a man, which validates His role as a compassionate advocate for us. Hebrews 4:15 highlights that He was tempted in every way yet without sin, combining His perfect humanity and divine nature. This profound understanding offers believers assurance that their petitions are heard and valued because they come through the One who experienced life on earth just as we do.
