Here's some important food for thought - a question all Christians need to be able to answer:
Is Christianity objectively true, or subjectively true?
In other words, is the truth of Christianity like, say, the truth that a water molecule consists of two atoms of hydrogen and one atom of oxygen? Or is Christianity just "true" like the statement "Vanilla ice cream is the best" is "true" for some people?
Do the truth claims of Christianity - such as that God created the universe or that Jesus was a real man who actually died and came back to life - reflect reality? Or is Christianity just something you believe if you like it or want it to be true or if it works for you?
If Christianity is objectively true, then how should we be convincing others that it is true? By sharing our subjective experience, or by providing objective evidence? By explaining why it's our favorite flavor of religion, or by showing that it accurately reflects reality? By talking about how it works for us, or by giving arguments that can be verified objectively?
How are you convincing those around you? And what does that say about how you see the truth of Christianity?
