People live for several reasons. Some wanna just make money and that's all they care about; many others are already swimming in money, and they feel that's all life is about. There's nothing you tell them that would move them.

From the onset, humanity had always looked for means to get connected to divinity. Diverse methods were adopted, just to be able to seek for answers to life's matters.
If you are a believer in Christ, kindly try to imagine what would life be in the absence of Christ. I am sure, Aimless, Worthless, Meaningless, Useless, right? If not for or because of Christ, why are we still living, or even alive?
