Jesus healed people physically as a sign of healing people spiritually. He opened the ears of the deaf and freed the tongues of the dumb and speech-impaired as a sign that He would open our ears so that we can have a greater faith and open our mouths to proclaim that faith (see Mk 7:35).
Our spiritual deafness, dumbness, blindness, and paralysis are worse than terminal. They are potentially damning. We are in impossible circumstances. We live in incurable, potentially devastating spiritual conditions. However, Jesus is our Hope, our only Hope, and His continuing ministry of healing expresses that hope and points to its fulfillment in the sacrament of Baptism.
Healing accompanies the proclamation of the gospel, leading to faith and Baptism (see Mk 16:17-18). Then Baptism leads us to receiving and giving Jesus' ministry of healing, which further leads us to participate in Jesus' ministry of hope leading others to faith, salvation, and Baptism.
At Baptism, we pray Jesus' prayer "Ephphatha" (see Mk 7:34). This is the ultimate opening. The baptized have spiritually opened ears, mouths, eyes, and hearts. May healing lead to and from Baptism.
