There is little merit in thinking of God as an idea if He is in fact a person. You can come to accept an idea and still be no closer to meeting the person.
We live in the age of relativism. What’s right for me is right for me and what’s right for you is right for you, but you know what all that really boils down to? An innate, inner desire to have ultimate authority over our lives.
The relativist looks at the world around them and says: If I see it, if I feel it, if it’s within my realm of experience, then it is truth. Right and wrong can be whatever I want them to be.
Even Christians are far more prone to this than we like to think. Sure we look to the scriptures, but too often we hold them in one hand, balancing them against a hand piled high with reason, experience and feelings.
This makes me think of one of my favourite quotes by Tozer: ‘[The scholar] may compare scripture with scripture until he has discovered the true meaning of the text. But right there his authority ends. He must never sit in judgement upon what is written. He dare not bring the meaning of the Word before the bar of his reason. He dare not commend or condemn the Word as reasonable or unreasonable, scientific or unscientific. After the meaning is discovered, that meaning judges him; never does he judge it.’
May we never bring the Word of God under the judgement of our own corrupt reasoning.
