Read 1 Peter 3:13-16
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 – 1 Peter 3:15b (NIV)
As we try to relate in love to everyone who crosses our path, we may nevertheless encounter resistance or hostility at times. The first thing to do is to check our attitude—are we acting and speaking with gentleness and respect? If so, then realize that they are rejecting God, not us, forgive them, and let God worry about their response. His Spirit can bring conviction and prepare their heart for their next encounter with you or another Christian.
