1) All theology is bad!
Some Christians are somewhat anti theology, which might seem odd at first, but is understandable when you are perhaps an evangelical Christian reading what has been written by Liberal theologians. Therein lies the clue, actually Christians should not be against theology, the issue is some theologians and the practice they follow. To know God starts with a right response to the basics of the gospel.
Theology is at it's heart the knowledge of God, or about God, which is right at the heart of the gospels and all the rest of scripture supports this. Knowing about God and getting to know God is indisputably a good thing which all Christian believers can agree on. Therefore at its heart theology is good.
2) All theology is hard to comprehend.
As with all misconceptions there is a kernel of truth here, but the issue is humans trying to understand God (who is way above our intellectual pay grade) and then to explain what they have learned to other people. However at its most basis day to day level theology is not complex, Christians have the Bible and above all Holy Spirit to help us understand what we need to know and do. Too many people are scared of looking deeper into their faith, saying I'm not clever enough to understand, completely discounting the fact that they have the supreme intellect at work within them...we often focus too much on our IQ and don't listen enought to 'The Helper'.
Theology can be intellectually challenging the deeper you get. God wants us to learn to ride a bike, he does not want us to compare ourselves to the unicyclist juggling whilst on a tightrope, He wants us to learn to cycle for use in day to day life first and foremost. Getting to know God is a day to day life skill, not just an ethereal academic pastime.
3) Theology will weaken you faith.
Bad theology might, but actually living the Christian life without getting to understand God as revealed by scripture is a pretty good way of undermining faith too, as it inevitably leads to problems which quickly erodes or worse builds faith on errors, with inevitable problems arising as a result.
Theology will challenge what you believe, it will winnow your ideas, and some chaff will have to go. But pursued properly studying God and scriptures will see the pruning of your ideas lead to newer stronger growth. In the short term your faith might feel a little wobbly as the dross is removed, but what will remain will be purer and eternally enduring.
The key to all of this is spending time with God regularly, studying His word and listening to His Spirit. Ask Father to show you how to study, which authors to read, seek council on where to study if you are going to pursue it at that level.
We have nothing to fear from theology done properly and a great deal to gain from doing it well.
Let us learn to embrace theology at its heart as we press on to learning more about our wonderful God.
