Christ with us always?

Read this passage from 2 Peter 3:

Since all these things are to be dissolved in this way, what sort of people ought you to be in leading lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be set ablaze and dissolved, and the elements will melt with fire? But, in accordance with his promise, we wait for new heavens and a new earth, where righteousness is at home. Therefore, beloved, while you are waiting for these things, strive to be found by him at peace, without spot or blemish; and regard the patience of our Lord as salvation (verses 11-15a)

Do we hear fear at the discussion of end times? Is that the right response to this passage? Do we miss the command to live our lives in a way which demonstrates our conviction -- our core belief -- that Christ lies and reigns in our lives. how would we live if we believed he might walk in our door -- tomorrow? Today, even? Shouldn't we be living a life that says that Christ is with me always? We say we believe that, but do our actions demonstrate -- provide a witness -- to that belief?
