2 Corinthians 4:16-18

So we do not give up. Our physical body is becoming older and weaker, but our spirit inside us is made new every day. We have small troubles for a while now, but they are helping us gain an eternal glory that is much greater than the troubles. We set our eyes not on what we see but on what we cannot see. What we see will last only a short time, but what we cannot see will last forever.
