Matthew 10:14-15
14 And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
15 Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.
I have preached sermons to where the congregation listens and seem to be on the edge of their seats. Then, I have preached sermons to where it seemed not one person was paying attention. They did not want to listen and hear what I had been lead to preach. Either way I preach my message and then move on. We have to realize that there will always be those who decide they do not need to hear what we have to say. Do not get mad nor discouraged, just do what God has sent you to do. If you are preaching or teaching the truth it falls on them to accept it and study it. Once you are done move on to the next place God is sending you. You see the people who ignored you may not think you are old enough or wise enough, so they choose not listen. However, they may continue to watch you just to see if you walk the walk. So, shake the dust off and keep moving.
