Systematic theology answers the question, “What does the whole bible teach us about a particular topic.” Instead of finding an answer with one particular bent, we look at the entire range of scripture, in the context that it was written.
We need to study theology for a number of reasons.
1.) It’s part of the Great Commission. In Matthew 28:18-20, Jesus commands us to “Go and make disciples… baptizing them… teaching them…” The task of fulfilling the Great Commission includes teaching the nations about what the Bible says to us.
2.) It helps us to overcome our wrong ideas – we all study the Word with a particular bias, and seeing the full collection of scriptural reference allows us to overcome this.
3.) We can make better decisions – “In every area of inquiry, certain theological principles will come to bear, and those who have learned well the theological teachings f the Bible will be much better able to make decisions that are pleasing to God.”
4.) It helps us grow as Christians – the more fully we understand God, the more mature our responses to him become.
We study systematic theology, noting the following:
1.) We should study it with prayer – head knowledge can make us smart while leaving our lives unchanged. Doctrinal errors will occur where study is not partnered with intimacy with Jesus.
2.) We should study it with humility – 1 Peter 5:5, God will oppose the proud, but give grace to the humble. We shouldn’t let our knowledge about the things of God cause us to misrepresent the character of Christ.
3.) We should study it with reasoning – God gave us logic, and so we can make deductions from scripture with a clear conscience, as long as they do not contradict anything else in Scripture.
4.) We study it with help from others – community allows us to learn and grow together, because our collective experience causes individual growth.
5.) We study it holistically – we need to collect and understand all of the relevant passages of scripture on a topic, so that we get the whole view.
6.) We study it with happy hearts – “We must love all that God is, all that he says, and all that he does.” Our studies of intellectual matters shouldn’t kill our passion!
