Read 1 Peter 3:15, "but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence."
If someone asked you why you went to church, what would you say? If somebody asked you how you know for certain that Jesus is the only way, would you know how to respond? What if someone asked you why God lets bad things happen in the world? If you live your faith openly (which is really the only way Christians are to live it), then you will come across some questions and raised eyebrows. How will you respond to this?
Peter is instructing us in this verse to be proactive. When someone asks us about our faith, we need to be prepared. Have you ever been speechless when someone asked you a question, and then thought of the perfect response minutes later as you were walking away? I know I have! The reason we can't think of a good response right away, is because we're caught off guard. If we follow Peter's instructions in 1 Peter 3:15, we won't be surprised and consequently miss opportunities to share our faith.
We're told in this verse to be ready to make a defense of our faith. But how do we get ready? The number one way to get ready is to be an avid reader of God's Word. We can't defend our faith if we don't know the Bible, because all of the answers to people's questions about Christ are found in it! Read it over and over again, not letting a day go by without looking over at least a few verses. The more you read it, the more you will remember it. Memorize key verses (Romans 3:23, 6:23; John 3:16; John 14:6; Eph. 2:8-9, etc), and underline many others in your Bible, so you can reference them quickly. Having a Bible with you either in your car or backpack, will keep you ready to reference Scripture at any time. In addition to the Bible, read and study other non-fiction Christian books by trusted authors. Being well-read is a great way to be ready!
Another way to be ready to give a defense of your faith is to pray. Pray for opportunities to share your faith, for the courage to seize those opportunities, and for wisdom to know the right words to say. We must be totally dependent on prayer to share our faith; it is vital for us to rely on the Holy Spirit fully. I can't stress this enough! If you try to witness on your own strength, without prayer, then you won't be effective. A praying person is a ready person!
Finally, don't forget the very important clause at the end of this verse, because it will make all the difference. As you give a defense for the hope that is in you, do so "with gentleness and reverence." The purpose in giving a defense of your faith is not to prove that you're right and they're wrong, to argue someone into taking your side, or to make others look stupid or ignorant with all of your fancy arguments. You should give a defense out of love and compassion for the lost, not out of a desire to be right. Rather than arrogant or condescending, your attitude should be gracious and loving. Be gentle and reverent, not a harsh know-it-all. There's a big difference there!
Are you ready at any moment to give others a reason for the hope that you hold so dear? Being taken by surprise and missing an opportunity to share your faith is a horrible feeling. I know, because it's happened to me. By studying the Word and immersing yourself in prayer, you will be armed and ready for anything~
