No! Christian apologetics is certainly not summarised that way. What then, is it?
"You shall know that truth..."
These famous words spoken by Jesus Christ in John 8:32 give us a clue. So when someone asks you why you follow Jesus Christ and not any other 'god' or 'godman' ("after all, even they do miracles") you need not just say "Jesus has changed my life completely, for the better." Because many people may not be convinced by that answer. Thankfully God - knowing the human mentality - gave us hardcore evidence to prove that Jesus Christ existed, was crucified, buried in a rich man's tomb and resurrected. He gave us historical, archaeological and statistical proof that what the Bible says is indeed true. But unless you are aware of these proofs, you won't be able to convince skeptics, apart from the Holy Spirit opening their eyes.
I urge you to equip yourself not only in the Bible, but also in knowledge that you can have handy, when confronted with questions about your Christian faith. Some good online resources are:
In fact, Apologetics315 is actually an apologetics aggregator blog, that gives you links to many other relevant websites, podcasts etc. Most - if not all - of the material on these sites is free. If you prefer to have your apologetics material in book form, you can visit Christianbook.com and buy your stuff there.
Important: Even after you have given all the evidence in the world to a skeptic, it is only the Holy Spirit who can open the person's spiritual eyes. So as you share information and minister to these precious souls, pray in your heart for God to touch their hearts with the same love, mercy and grace that He showered upon you that day when you gave your heart to Jesus!
