Now that we know what theology is, let’s look at the reasons why Christians should study theology.
Reason 1: Everything is theological
All the 'big' questions of life can be answered by a theological understanding.
- Does God exist?
- If God exists, who is He and what’s He like? What does He want from us?
- How are we humans to respond to Him?
All these questions have a theological answer.
Reason 2: To know what you believe
and why you believe it
Sadly, many Christians have never taken the time to think through what they believe, which can be dangerous. Just because I believe something doesn’t necessarily make it the case. Christians are called to study so
they can "correctly handle the word of truth" (2 Timothy 2:15). Moreover, studying what we believe, and why we believe it, helps us recognize how Christianity is different from other worldviews and religions in the world.
Reason 3: To defend
the faith and guard against false teaching
Not only should Christians know what it is that they believe and why they believe it, it’s also important for Christians to know these things in order to defend Christian truth claims (apologetics).
Jesus’ disciple, Peter, tells believers that they are to “be prepared” and “make a defence” for the hope that they have (1 Peter 3:15). Jude, Jesus half-brother, calls on Christians to “contend for the faith” (Jude
3). Jesus warns believers to watch out for false teachers. Sometimes they may look like sheep, but often they’re wolves in disguise (Matt 7:15). Paul, too, tells believers to watch out for “vain” philosophies that are grounded in “human
tradition” and not Christ (Colossians 2:1-4, 8). So theology helps us to be wise to error.
Reason 4: Our beliefs shape our actions
In the book of Romans (Romans 12:1-2), Paul urges Christians not to “conform” to
how the world works and thinks. But how are Christians to do this? By renewing their minds! Renewing our minds transforms us. Prayer, study, worship, and reflection are all ways in which we renew our minds. When we engage in theology, we are participating
in renewing our minds by studying and thinking hard about God, his world, and God’s work in the world. We are in fact worshipping God with our minds.
Reason 5: Theology keeps us right when interpreting texts
This is so important. When
we have an understanding of the overall picture then when we come to an individual text or to understand a prophecy or texts that are difficult to understand then when we apply our theological overview and understand the big picture then things become clearer.
REASON 6: As a means to help worship
Theology is ultimately about worship. When asked by a teacher of the Jewish law about which of the commandments was the greatest, Jesus responded by
saying that we are to love God with every ounce of our being—including our minds (Mark 12:28-30). Everything that we do should be done in order to know God and to glorify Him through our lives. Also we are commanded in worship to love the Lord
our God will all our MIND, heart and strength. Theology has to do with the mind and helps us worship God in our minds
