Reason 1: You Have Nothing to Lose.

Gambling is defined as a chancy venture where something is risked on an unknown outcome.  On any uncertainty you can bet small or large - but are you willing to bet your life on one toss of a coin or roll of a dice?  Most would not be so foolish.    

Those who don’t believe in God are betting ‘everything’ on when they die there is ‘nothing’ and they will simply cease to exist.  But:
WHAT IF death isn’t the exit door to your existence? 
WHAT IF you have a soul that continues into eternity? 
WHAT IF there is a meaning to life?
The truth is no one can physically prove God exists, but equally no one can prove that He doesn’t.  Objective scientists admit they have so few answers as to what life is about.  The more they learn about the universe and the miracle of existence the more questions that arise.  Most scientists realize their ever-changing theories of origins are based on missing or debatable evidence.  In the end, people reject God and accept evolutionary theories simply on the bases of probability – a gamble. 
Are you certain enough to gamble everything on a belief that there is no God; that life is simply a miraculous cosmic accident and there will be ‘nothing’ when you die?  A wise gambler once wrote, ‘I would rather live my life as if there is a God, and die to find out there isn’t - than to live my life as if there isn’t, and die to find out there is.’
Believing in ‘nothing’ is the ultimate gamble.  If you are right, in the end there is nothing – fine. If you are wrong – you will eventually come face to face with God, who you rejected.  
The Bible states we were created with a soul that continues after death and we were created with free-will that God must respect. The Bible further states mankind was separated from God through bad choices (sin).  God, not wanting anyone to perish, took on the form of a man (Jesus Christ) and payed the complete penalty of sin on the cross.  Now, eternal salvation (a restoration of our relationship with God) is a matter of personal choice.  It is up to you. …God demonstrates His love towards us, in that while we were still sinners, Christ died for us (Romans 5:8). Believe on the Lord Jesus Christ and you are saved (Acts 16:31).
Believing in the Lord Jesus Christ may prove to be the best gamble you ever made. By believing in Him you have everything to gain and nothing to lose.
