If the man in Mark 10:43-48 would have listened to the crowd, he would not have received his healing. "Ye have not, because ye ask not" (Jas. 4:2).
This blind man is a good example of an active kind of faith. He was not passive in his approach toward healing. He boldly cried out to Jesus for mercy. When the crowd ridiculed him and told him to be quiet, he cried out even louder.
Many people believe that God can perform the miracle they need but relatively few are willing to actively pursue it until they get results. They are afraid of what others will think of them. This man had his attention focused only on Jesus. Nothing else mattered and that is why he got healed.
An important part of faith is seeking God with your whole heart. If we are concerned about what people think so that we can gain their approval, we will never take a stand in faith for anything that we might be criticized for.
This one thing has probably stopped as many people from receiving from God as anything else. You cannot be a "man-pleaser" and please God at the same time. Satan uses persecutions to steal away God's Word and stop our faith. To see faith work, we must say with Paul, "let God be true, but every man a liar" (Romans 3:4).
