v. 18-19 Jesus reads from a scroll of the prophet Isaiah (at this point He is very well liked). v. 21 Jesus told everyone in the synagogue "Today this scripture is fulfilled in your hearing." That must have been astounding to the people listening. The people had been waiting for Him and when He finally came they didn't see Him! v. 24 "No prophet is accepted in his hometown." When you become a Christian those around you will resist the most. The non believers will want the old you back and some of the believers might think that God couldn't possibly want you. The people closest to you know your background and your failures. So instead of many being amazed by your change they hate it. You might have to go through some terrible days but you may be the only one to plant a seed in someones life. You never know what impact you might have on someone if you can stick out the hard times.
v. 25-27 Jesus reminded the people of Elijah during the drought God had him go to a widow in Zarephath. There were many widows in Israel but God did not want him there. Also there were many people with leprosy who did not get healed. Only Naaman the Syrian was healed. You could drive yourself crazy trying to figure out why some get healed and others don't. Jesus angered the people because He was saying that God sometimes chose to reach Gentiles rather than Jews.
v. 28 The people were furious, they tried to throw Jesus off a cliff. We don't like getting confronted when our holiness is under question. We should see it as a learning experience that God might want us to grow in our faith.
You may be the only bible that some people read.
