If you do not love the truth, you will perish. And, when I say ‘perish’, I don’t just mean physical death.
If you do not love the truth, you will perish for all eternity.
And yes, the truth really is that important.
However, I will assume that you have already discovered the truth, and that you will be welcomed into the arms of our loving Father, when this life is over. So, I will turn our attention to the life that lies before you.
If you love the truth, you might live long enough to serve God to the fullest, and that is what we want.
For those who do not love the truth, they are left with Cognitive Dissonance and destruction.
