What does the Bible say about defending our hope in Jesus?
1 Peter 3:15
...in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you...
John Piper walks us through the context of the verse, showing that the death and resurrection and coming return of Jesus are the basis of our faith and hope. We are always with God now and all things are working for our eternal good.
