1 Peter 3:15 

“But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.”

• The phrase “give an answer” (Greek: apologia) can also mean a defense or explanation—apologetics
   

2 Timothy 4:2 

“Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching.”

• Proclaiming truth consistently, whether it’s convenient or not
