God Is Not Dead Yet
How current philosophers argue for his existence.
William Lane Craig posted 7/03/2008 10:50AM

In a recent article, University of Western Michigan philosopher Quentin Smith laments what he calls "the desecularization of academia that evolved in philosophy departments since the late 1960s." He complains about naturalists' passivity in the face of the wave of "intelligent and talented theists entering academia today." Smith concludes, "God is not 'dead' in academia; he returned to life in the late 1960s and is now alive and well in his last academic stronghold, philosophy departments."

The renaissance of Christian philosophy has been accompanied by a resurgence of interest in natural theology, that branch of theology that seeks to prove God's existence apart from divine revelation. The goal of natural theology is to justify a broadly theistic worldview, one that is common among Christians, Jews, Muslims, and deists. While few would call them compelling proofs, all of the traditional arguments for God's existence, not to mention some creative new arguments, find articulate defenders today.

some arguments given in the article are

The cosmological argument
1. Everything that exists has an explanation of its existence, either in the necessity of its own nature or in an external cause.
2. If the universe has an explanation of its existence, that explanation is God.
3. The universe exists.
4. Therefore, the explanation of the universe's existence is God.

The kalam cosmological argument
1. Everything that begins to exist has a cause.
2. The universe began to exist.
3. Therefore, the universe has a cause.

The teleological argument
1. The fine-tuning of the universe is due either to physical necessity, chance, or design.
2. It is not due to physical necessity or chance.
3. Therefore, it is due to design.

The moral argument
1. If God does not exist, objective moral values and duties do not exist.
2. Objective moral values and duties do exist.
3. Therefore, God exists.

The ontological argument
1. It is possible that a maximally great being (God) exists.
2. If it is possible that a maximally great being exists, then a maximally great being exists in some possible world.
3. If a maximally great being exists in some possible world, then it exists in every possible world.
4. If a maximally great being exists in every possible world, then it exists in the actual world.
5. Therefore, a maximally great being exists in the actual world.
6. Therefore, a maximally great being exists.
7. Therefore, God exists.

He continues

Christians who depreciate natural theology because "no one comes to faith through intellectual arguments" are therefore tragically shortsighted. For the value of natural theology extends far beyond one's immediate evangelistic contacts. It is the broader task of Christian apologetics, including natural theology, to help create and sustain a cultural milieu in which the gospel can be heard as an intellectually viable option for thinking men and women. It thereby gives people the intellectual permission to believe when their hearts are moved.
