Mockers have been around for thousands of years. These are the people who will always want to ridicule and tear down anyone who has a different perspective on life. 

Unfortunately, their numbers will continue to grow and they will become more aggressive as we come closer to the last days as recorded in the bible.

Listen to how they mock the return of Jesus Christ in.

2Pe 3:3 knowing this first, that in the last days mockers will come, walking after their own lusts. 

2Pe 3:4 and saying, "Where is the promise of his coming? For, from the day that the fathers fell asleep, all things continue as they were from the beginning of the creation."

Jesus Christ will return in God's own time, not ours. There are many signs that will become more obvious as time goes by. Just one of these signs is these mockers will become more vocal and aggressive the closer we get to the return of Jesus Christ. Mockers being present is only one of many signs we must be aware of if we are to be prepared for Christ's return.
