The Bible says that you should be "ready to make a defense before everyone who demands of you a reason for the hope you have, but doing so with a mild temper and deep respect." (1 Peter 3:15) Therefore, give attention to two factors - what you say and how you say it.
Baebele ya re o tshwanetse go nna o "iketleeleditse go iphemela fa pele ga mongwe le mongwe yo o lo batlang lebaka la tsholofelo e e mo go lona, mme lo dira jalo ka bonolo le tlotlo e e boteng." (1 Petere 3:15) Ka jalo, ela tlhoko dintlha tse pedi  - se o se buang le kafa o se buang ka teng.
