This passage in some ways presents to us the tale of two daughters. One is a young girl around 12 years old who was dying. The other is an older lady who has suffered for 12 years with a chronic bleeding issue. Both needed healing. Both needed Jesus. Jesus’ call in both situations is the same: believe.
Jesus tells the older woman that her faith has made her well. Jesus tells Jairus to believe and his daughter would be well. The woman believed Jesus could heal her and He did. Jairus believed on behalf of his daughter. His faith made her well.
To be sure, Jesus was the one who healed these women. We must however recognize that the conduit through which the healing came was the faith of those involved. In Matthew 13:58 we see that Jesus did not many miracles in His hometown of Nazareth because of the unbelief or lack of faith of those who lived there. Faith is the means God uses to accomplish amazing things.
All throughout Scripture, God calls people to respond in faith. It is through faith that we come into a relationship with God and receive forgiveness of sins. It is through faith that we persevere and grow in our relationship with Him. And it is through faith we receive the fullness of life promised by Jesus.
There are many things that may cause our faith to waver. These two situations would probably do that to most people. However, their example of believing in spite of their circumstances encourages us to “...live by faith in the Son of God who loved me and gave Himself for me.” (Galatians 2:20)
What in your life is causing you to lose faith? Ask the Lord to increase your faith in Him.
