1 Peter 3:15 (KJV) But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:
“Sanctify the Lord”– see the use of the word “sanctify” here. It means to set the Lord apart from everyone else to be the one we worship, adore, and obey. We must consciously, willingly, continuously make Him Lord in our hearts.
“Always be ready”– We should know why we are believers in Christ and why we have our hope in heaven, and we should be able to tell others about it in a clear and convincing way.
Always have the Lord’s name ready to tell others your reasons for hope. Always. However, it is important to remember what the Bible tells us in James 4:10 : “Humble yourselves in the sight of the Lord, and he shall lift you up. ” Do not use the Lord’s name with arrogance or aggression. Be meek and gentle when using his name, as the Lord did when he sent Jesus Christ to earth.
