Luke describes the woman as crippled by “a spirit of infirmity eighteen years” and “bound” (verse 16) by Satan. Without denying the historicity of the event, Luke's placing this miracle at this point in his narrative has obvious symbolic value. Jesus' mission among the Jews was to “loose” them from crippling influences and bring them to uprightness. This miracle is a graphic example of Jesus making a literally crooked woman upright.
Jesus healed her by His words and by touching her. He could have healed her by a word only, and as seen in other miracles, He did not even need to be in the same place, city, or country. However, in laying His hands on her, He shows everyone the value of her obeying God and coming to Him. Had she refused, He could not have touched her. Nothing good comes to those who disregard God's Word (Romans 2:8; II Thessalonians 1:8; I Peter 4:17).
People often pray for the “touch” of God upon their lives, which is not a bad prayer. Yet, if we want God to touch us, we must draw near to Him. We cannot keep our distance from Him in fellowship. We must walk closely with Him at all times if we want His influence upon our lives.
