God does not call us to a blind faith. In the book of Acts in the New Testament, we see where Paul “reasoned with them” in some cities in Greece, speaking both to Jews and Greeks. Jesus tells us to “Love the Lord your God … with all your mind.” This is the title of a great book by J. P. Moreland, where he quotes J. Gresham Machen: “False ideas are the greatest obstacle to the gospel.” And he quotes the scholar, John Stott, who was asked to reflect on his 50 years of ministry: “My exhortation would be, Don’t neglect your critical faculties. Remember that God is a rational God. That God expects us to explore His double revelation, both in nature and in scripture, with the minds He has given us.”
It reminds me of a quote from Galileo, who wrote in 1615: “I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.”
I used to tell our daughters as they were growing up, to inquire to see if what I was telling them about the Universe, about humanity, about heaven and about God was true. I would often challenge them to “check up on Dad”. Not to just blindly believe what I told them about God. I would invite them to have their own true personal, spiritual faith-experience with the Father.
So don’t check your brains at the door, when it comes to discussions of faith, origins and purpose. God did not put that nagging feeling about “something more” in life to frustrate you.
No, that feeling is there to move you on to the Great Adventure, an adventure of faith with God himself. To have a personal experience with God is reasonable. It’s what you are designed for.
