2 Peter 3:11

Since all these things are to be destroyed in this way, what kind of people ought you to be (in the meantime) in holy behavior (that is, in a pattern of daily life that sets you apart as a believer) and in godliness (displaying profound reverence toward our awesome God),

We will know the signs of the return of Jesus and need to build up our confidence and behavior.  As believers, we have come so far but need to finish this race, not in fear but continually striving to be doers of the word until Jesus appears. We need to guard our hearts and strengthen ourselves and encourage each other in the Lord.
