Systematic Theology 9: The Existence of God

How do we know that God exists?

This week see’s us start part 2 of Wayne Grudem’s systematic theology. So far we’ve covered The Doctrines of the Word of God. And now, we are looking at the Doctrines of God.

My mentor once told me, systematic theology studies are usually divided over what to look at first. God or the Bible. It’s a bit like the chicken and the egg. Theology is, by definition, the study of God. So intuitively we may assume the Doctrine of God should be studied first. However, since Systematic Theology is our knowledge about God as defined by the whole of scripture, it is important that we establish what Scripture claims for itself first.

In short, it doesn’t really matter, and there is a lot of overlap.

Reading chapter 9, felt a little like re-visiting my RE classes back in secondary school.

Wayne Grudem outlines four main approaches to believing God’s existence.

1) Our inner sense of God (which is intensified by the Holy Spirit for Christians, and alluded to in Scripture – see Romans 1:19,21,25)

2) The Evidence of God in Scripture and Nature (we are told the heavens declare God’s glory, that the seasons of fruitfulness demonstrate His mercy – see Acts 14:17 & Psalm 19:1)

3) The Traditional proofs – these were covered for most students in Religious Studies classes at school. A quick google search will find good elaborations on them. (Sorry I don’t have time now to re-hash them!) They included the Comological Argument (First Cause), Teleological Argument (Intelligent Design), Ontological Argument (The “Greatest” thing must be real in order to be the “greatest”) and the Moral Argument (see point 1).

Interestingly, Grudem concedes that these traditional arguments are true whether we are convinced by them or not. But that, they themselves, cannot bring to saving faith the lost. This is because of the Doctrine of the Sufficiency and Necessity of Scripture.

4) Finally, we are told that only God can overcome our sin (which blinds us) and enable us to be persuaded by His existence. 1 Corinthians 1:21 reminds us that human wisdom is inadequate, we are dependent on Him to bring us life.

Not losing the Intimacy

It’s been an interesting transition the last few weeks, I’ve made a move to combine blogging with my walk with God. And there have been some great benefits to doing this:

  1. Consolidating my thoughts
  2. A mild form of accountability
  3. Future Benefits – I’m creating a resource to look back on and use later.
  4. Encouraging others – at least I hope so!

However one main concern has surfaced fairly quickly. I do not want to sacrifice the intimacy I have with God during my quiet times because my mind is elsewhere, thinking about how every thought and idea could be transposed into blog format!

It was an issue I found, as a teenager, when I decided to start a weekly gathering for other young guys at my Church. I would be churning through Bible readings, sermon podcasts and books to glean material for the next meeting.

This is not the point of reading the Bible, prayer or listening to sermons. I don’t read the Bible to become a “man of the word”, I don’t pray to become a “man of prayer”, I don’t listen to talks to regurgitate the latest insights. I engage in these activities to nurture my relationship with God, to become more like Jesus and to better equip myself to serve, encourage and love others.

So how do I fight for intimacy whilst at the same time seek to lead, labour, inspire and encourage others? How do I fight to keep my relationship with God from becoming a transactional encounter? What have I learned over the last couple of weeks?

  1. I journal my prayers – a few years ago I was having coffee with a mentor and he pulled out of his bag a proper looking leather bound journal. It was like something out of Lord of the Rings! He opened it up and told me to read one of his prayers, while he went to order another coffee. Just holding that journal was precious, and I could see later as he flicked through it that the pages were filled with numerous prayers. A few weeks later and I’d ordered my own. So what with note-taking, blogging and journaling, there is a lot of writing in my times with God. But this is helpful for me, it helps me to remember, to process and to express myself. It also helps my mind to focus when I’m talking to God, it’s difficult to write and think about breakfast (or fall asleep!) It also slows down my thinking, so that I can invite God to interrupt the chaos in my mind.

Journaling allows me to keep the intimacy in the midst of blogging, because it keeps a part of my relationship with God hidden and secretive.

  1. I take my time. Before I started seriously studying God’s word, my morning routine was packed with 4 main activities. Exercise, Time with God, Writing, and reading. I’d give about 45-60 minutes to each all before work started. Now, I’ve reduced my morning routine down to two items. 1) Running and Weightlifting, 2) Time with God. And so each morning I’m getting a solid chunk of time uninterrupted to study, to pray and to process God’s word. It has been so refreshing, and I think one of the most helpful things towards this is: that I have set aside the space so that I can take my time.

You’ll have also noticed I’m only publishing 3x study blogs a week. This means there is very little pressure to post every day what God’s teaching me. There is room, and time, to wrestle with God through private issues. And scope for me to spend mornings simply being with God. It’s so good! And I would highly recommend it.

  1. I listen to God’s Spirit. I believe it was He, who made me aware of the dangers of losing the Intimacy in the first place. He, who bought it to my attention so that I could counterbalance the dangers, and protect myself. It will be Him, who will guard my heart and mind and bring me to maturity.

May I continue to choose what is better, like Mary, and sit at Jesus’ feet. Rather than being distracted by all the “preparations”, the work, the ministry.
