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 he 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.
“ Be ready always ”– 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.
We have to keep God first in our lives; it’s the only way we can truly live as Christians. Not only are we to do that, but we have to know why we have chosen to follow God. This life isn’t a life of blind faith. We should be ready to defend our faith to anyone who challenges it. We should also be ready to explain, to anyone who enquires of our faith, in hopes that they will be inspired to receive salvation too.
