Often atheists will associate all religions with being cults. In this video Hemant Mehta, an atheist YouTuber and blogger gives what I believe is a fair assessment of the differences between cults and religions.
One of the many objections we as Christians bring up in opposition to an atheistic worldview is that life cannot have purpose. If there exists no creator, no one that created humanity with a specific design with a specific purpose then we cannot go on to say that life has any real purpose or meaning. In the end we must simply eat, drink and be merry for tomorrow we die and there is nothing left after that.
Atheists object to this point saying that they can create purpose themselves. They can create purpose by creating their own goals, their own wants and achievements. But does this really amount to anything?

I think there are many Christians who feel intimidated to talk to Jehovah Witnesses’ and Mormons. Most of the time we realize that the missionaries from those religions have done a lot of studying and preparing to share about their faith and we find that intimidating because we feel like we haven’t done much of that ourselves. But I wanted to challenge you to think of this differently.
Many religions in the world claim to be the true one. Of course we know that not all them can be true, because they contradict. Islam says Jesus isn’t God, Christianity does. Hinduism says hell doesn’t exist, western religions do. Buddhism says this world is an illusion, Judaism says that God created the very real world that we see. So how do we determine which one is true?
