How do we know Jesus is able to heal us spiritually?

Jesus' miracles portray his ability not only to cure physical ailments but also to heal spiritually. When he healed the deaf and dumb man, he touched the man’s ears and tongue to signify the spiritual healing that accompanies physical restoration. The Lord’s commands—such as 'be opened'—reflect the power to bestow spiritual understanding and insight, emphasizing that true healing originates from God’s grace. Furthermore, these acts serve as a testament that Jesus is the one who opens the hearts and minds of people to receive his gospel, illustrating that spiritual awakening is a work initiated and completed by Him through the sovereign flow of his will.
