This question already has an answer here:
There are numerous instances in the gospels of Jesus healing someone, and then Jesus in some form or another instructing them to keep silent about it. One example, in Matthew 9:27-31
27 As Jesus went on from there, two blind men followed him, calling out, “Have mercy on us, Son of David!”
28 When he had gone indoors, the blind men came to him, and he asked them, “Do you believe that I am able to do this?”
“Yes, Lord,” they replied.
29 Then he touched their eyes and said, “According to your faith let it be done to you”; 30 and their sight was restored. Jesus warned them sternly, “See that no one knows about this.” 31 But they went out and spread the news about him all over that region. (emphasis mine)
Why did Jesus not want them to proclaim their healing? It doesn't make sense to me, as anyone who was healed of a lifelong malady would naturally want to tell all their friends & family. Was this just him making a point about how silly it would be not to share what God has done for us (e.g. the gospel) with others? Or is it something else?
