How do we know that Jesus' sufferings were voluntary?

The evidence of Jesus' voluntary sufferings is vividly illustrated in His Passion. As illustrated in the sermon, Jesus, under immense mental and physical strain, experiences a profound agony that causes Him to sweat drops of blood. This reaction demonstrates the weight of sin He bore for humanity. Furthermore, the metaphor of the gum tree which yields sweet spices without cuts emphasizes the voluntariness of Christ's sufferings—His sacrificial love flowed freely, without coercion. He chose to bear our sins, showing His fundamental love for mankind. This voluntary offering not only highlights His commitment to fulfill the Father’s will but also underscores the depth of His love and sacrifice for us.
