The Cross is the means of salvation. When Jesus tells us to take up our cross and follow him, he is not talking about burden but about salvation. Unless we take up the Cross and see that the yoke is easy and the burden light, we will have no share in his Kingdom.
Therefore we hold it high and honor it because such a thing has set us free, free to live a life of love rather than a life of sin.
If we ever took the time to think about sin in its rawest form (and we should) we might attempt to convey what Dante does through his magnificent work - no glamor, no reward, no peace.

― Dante, Purgatorio, IV 85-95
