Miracle stories like this one - a healing story - plus miraculous deliverances from foul spirits, resuscitations, and miracles involving nature - comprise over 200 verses in Mark's gospel.
That's more verses than the passion narrative -- the stories of Jesus' betrayal, trial, crucifixion, and death -- combined.
Let that fact sink in for a second.
Consider the fact that miracle stories are the subject matter of almost half the gospel prior to Jesus' arrival in Jerusalem.*
That points to a truth we often miss: God's desire for us human beings is for healing, wholeness, forgiveness, and joy.
Healing, wholeness, forgiveness, joy is what the author John Eldredge refers to as the "major theme" of the gospel. As opposed to the "minor theme" of the gospel which is sickness, brokenness, sin, and suffering.
