"Christian apologetics is the theological discipline of providing a reasoned defense and explanation for the truth of the Christian faith, using scripture, logic, and evidence to address objections and present Christianity as a reasonable belief system, rooted in 1 Peter 3:15's call to "always be prepared to give an answer for the hope that is in you" with gentleness and respect. It involves defending Christian doctrines, challenging opposing worldviews, and helping believers understand and articulate their faith, rather than seeking personal apologies." [Google]
