37 They did not believe in Him, although He had done so many miraculous signs before them.
38 This was to fulfil the word that Isaiah the prophet spoke: “Lord, who has believed our report? And, Lord, to whom has the arm of the Lord been revealed?”
39 Therefore, they were unable to believe, because again Isaiah said:
40 “He has blinded their eyes and had hardened their heart, so that they should not see with their eyes and understand with the heart, and turn, and I would heal them.”
41 Isaiah said these things because he saw His (the glory of Jesus) glory and spoke about Him.
Signs and wonders are a great means of demonstrating the power of God at work in the world. Yet they do not guarantee that people will come to faith in Him.
Many people witness the miraculous power of Jesus, both in their own life and in the lives of other people. However, this does not mean that they will all come to receive Jesus as their Lord and Saviour.
There was an occasion when ten lepers came to Jesus begging for healing, and Jesus sent them away to show themselves to the priest, and as they went they were healed. Yet of the ten who were healed only one came back to Jesus to say thank you and to give praise to God, and he was a foreigner (Luke 17.11-19).
We might be amazed that only one came back to give thanks and praise, yet this is a reflection of so many people. It would appear that there is an abundance of ‘take, take, take’, but a scarcity of praise and thanks.
In verse 37 John records much the same occurrence. There were many of the people who had seen the mighty works of Jesus. Perhaps a large number had benefited from Jesus feeding the five thousand with just five loaves and two fishes. Some would have seen Jesus heal the blind, and the lame. Many would have been there when Jesus raised Lazarus from the dead and call him out of his tomb.
Yet, they still did not believe that He had been sent from the Father, and that He is the Son of Man, the Messiah.
The signs and wonders of Jesus are an essential part of evangelism; they are a necessity for our life in the Holy Spirit. Yet they do not necessarily lead people to receive Jesus as their Lord and Saviour.
God wants to bless us with His miraculous power, and He has given to us the Holy Spirit gifts of miracles and healing, which we should eagerly desire. Yet, as we move and operate within these gifts, we must be aware that they may not lead others to come to faith in Jesus.
