Even in relativity theory even though you can analyze space - time in terms of this four-dimensional geometrical structure one of the dimensions is different. And this shows up in the equations. It has a different sign - rather than plus it shows up as a negative minus. So even in relativity theory time is distinct from space in terms of the way in which these dimensions manifest themselves in the equations.

Therefore, when a person refuses to come to Christ it is never just because of lack of evidence or because of intellectual difficulties: at root, he refuses to come because he willingly ignores and rejects the drawing of God's Spirit on his heart. No one in the final analysis really fails to become a Christian because of lack of arguments; he fails to become a Christian because he loves darkness rather than light and wants nothing to do with God.

Reason is a tool to help us better understand and defend our faith; as Anselm put it, ours is a faith that seeks understanding.

For the assertion that "There is no God" is just as much a claim to knowledge as is the assertion that "There is a God." Therefore, the former assertion requires justification just as the latter does.

The Christian faith does not call for us to put our minds on the shelf, to fly in the face of common sense and history, or to make a leap of faith into the dark. The rational person, fully apprised of the evidence, can confidently believe.

Our churches are filled with Christians who are idling in intellectual neutral. As Christians, their minds are going to waste. One result of this is an immature, superficial faith. People who simply ride the roller coaster of emotional experience are cheating themselves out of a deeper and richer Christian faith by neglecting the intellectual side of that faith.

Successful evangelism involves not only harvesting, but sowing and watering, too. We must never think that because a nonbeliever remained unconvinced by our case that our apologetic has failed. For one encounter is not the end of the story.
