Finding the right angle from which to approach an unbeliever can be tricky without guidance. Some people simply disbelieve God's existence, some believe in a different deity (or more than one), and some think that who they worship and who you worship are the same when it is plain to you that they are not. Unbelievers have problems with the reliability of the scriptures, the historicity of Jesus or the problem of pain and suffering. Knowing the basics of these issues and their biblical solutions can greatly enhance your introduction of evangelistic basics, tailored to each person's mindset. While apologetical arguments are not evangelistic techniques in the strictest sense of the words, the information presented here can go a long way in both your understanding of the worldview of the unbeliever and building your faith to accurately stand up to assaults of modern religions.
