That means that, on average, we only have about 70 years in this life to fulfill our purpose - to love, respect and obey the Almighty (Ecclesiastes 12:13). And I think it's high time that we take full advantage of that fact.
So many books, speeches, social media posts and other forms of media have surfaced urging people to look for their purpose in life. So many individuals have left their homes, careers and even families to "find themselves". And to be honest I can understand why!
"If you're not in Christ...you're wasting your time and you're wasting your life!" - Michael Whitworth
If it is our entire responsibility to obey God and respect Him as our Creator, Sustainer and Protector, and it is (cf. Ecclesiastes 12:13), then it's very simple to say that a person who is failing to do so is...
...missing their purpose in life.
But, God, the one who made us and therefore has the prerogative to tell us the point of our existence, has already made it perfectly clear that the only life worth living is the Christian life (John 10:10). Therefore, without Him your life is completely wasted!
