For most ideologies the axiomatic roots are in grow in the soil emotive experience.
A quick reminder of the revealed God of the Bible:
Matthew 10:29-31 New International Version (NIV)
Are not two sparrows sold for a penny? Yet not one of them will fall to the ground outside your Father’s care. And even the very hairs of your head are all numbered. So don’t be afraid; you are worth more than many sparrows.
This verse alone carries within it specific claims and claims that have an emotional weight with human beings. God is called Father. This Father cares for even birds. This Father knows the very hairs on your head. Be comforted for human beings are worth more than birds.
What specific claims with so much emotional appeal! God as Father is in itself an emotional and theological claim with huge implications to human psychology.
For God so loved the world that he gave his one and only Son…The Father loves the Son and has placed everything in his hands.
Again the Father loves the world! What we know of human history and natural history is this love? And everything has been placed in the Son’s hands. These are huge specific theological claims that are inherently emotional and are problematic when it comes to how human history and natural history have played out. Loving the world and having the world in your hands cannot be ignored if a person really wants to know whether this God makes sense in this world and Universe.
If God is to be understood through nature it is hard to see the Christian God as being conducive with that God construct. Charles Darwin used one family of parasitic wasps as evidence for natural selection, writing to a colleague:
“I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of caterpillars.”
When these specific attributes of the Creator are brought up then a person should question whether the knowledge of the natural world works well the description of this being. You can call that emotional but it is a rational response to emotional theological claims. It is intellectually dishonest to assert that those who reject these Christian claims are simply being emotional when those who accept these claims are also frail human beings with all the same emotional make up.
Many people are Christians not for Vulcan like logic but because of provincial social reasons that have much to do with psychological and emotional sources. Family bonds, parents, spouses, children, and the community have a great deal of influence on a persons emotional attachment to certain ideologies including Christianity.
Religion takes advantage of our emotions: our guilt, our fear, our solipsism, our shame, and our need for purpose and meaning in this life. The pillars of a human social life are covered with the vines of religious justification: Marriage, birth of a child, and the death of a loved one are infused with religious ceremony…how is this not an emotional advantage for the religious meme.
In fact the God of the Bible is quite emotional as well. God is loving, merciful, angry, jealous, and gets emotional with the people of Israel many times in the Old Testament. If William Lane Craig is to be critical of all this perceived emotional reaction perhaps he should start with the God of the Bible. The God of the Bible is from the imagination of emotional human beings and it shows.
