It is immoral to reject truth when it is offered to you.
It is just alike any other sin.
It leads to more sin.
One must close off part of his/her self in order to to reject truth.
One calcifies their own heart when you deny the life of goodness and truth that God offers.
Becuase God is truth, those who reject truth are rejecting God.
Brannon Howse in “UNDERSTANDING THE IMPORTANCE OF TRUTH” makes a good point: “Because God is truth, postmodernism is false because man did not create God. Postmodernism is the belief that truth is created by man and not discovered. How can man create God?”
He shows how rejecting truth leads to cultural decay and a failing nation.
