The better you understand where a person is coming from the better you will be able to communicate your faith to them. Because I am trying to give tips on defending the Christian faith my assumption is that you will be in a position where a person from another faith/worldview is in a give and take discussion with you. That isn't always the case, but it is a lot.
Part of defending your faith is knowing why the Christian faith is superior to any other worldview. If you truly believe that Christ reigns supreme over all other treasures you should be able to find where his gospel is better (yes it's ok to say something is truly better) than any belief you encounter.
Obviously I don't have nearly enough knowledge to talk about every worldview out there in detail but I can give some biblical help:
According to the Bible all mankind irrationally gives their worship to idols. Whether it's Animism, Hinduism, or plain old Atheism, worship that is not directed to the one true God of the universe is idolatry. Romans 1:18-32 gives us an overview of how this looks.
Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. (Romans 1:22-23)In our day and age this is seen in an inconsistency in morality (how does an Atheist know what is truly right?) only accepting religions that make you feel good about yourself (ask Hollywood for the best options), or simply find the religion that turns you into a deity (learn to ride a bike first). In Isaiah's day the criticism was that the same wood that was thrown into the fire to warm the house was also used to make an idol to which a person could bow down (Isa 44:15).
Am I suggesting you find the best way to tease a person about their personal beliefs, no. However, you should learn about other worldviews and understand where they fall short in comparison to the beautiful salvation that comes from Jesus Christ.
More to come...
