In the original language, 'Fear the Lord' doesn't mean be afraid. It means sustaining a joyful, astonished awe, and wonder before Him.
Timothy KellerWhile Christianity was able to agree with pagan writers that inordinate attachment to earthly goods can lead to unnecessary pain and grief, it also taught that the answer to this was not to love things less but to love God more than anything else. Only when our greatest love is God, a love that we cannot lose even in death, can we face all things with peace. Grief was not to be eliminated but seasoned and buoyed up with love and hope.
Timothy KellerI've heard plenty of Christians try to answer the why question by going back to the what. "You have to believe because Jesus is the Son of God." But that's answering the why with more what. Increasingly we live in a time in which you can't avoid the why question. Just giving the what (for example, a vivid gospel presentation) worked in the days when the cultural institutions created an environment in which Christianity just felt true or at least honorable. But in a post-Christendom society, in the marketplace of ideas, you have to explain why this is true, or people will just dismiss it.
