Dear Dan,
One of the ways to appreciate the meaning of the holy Cross in the life of Christians is to pray the Akathist to the Holy Cross.

Angels from Heaven invisibly circle the life-bringing Cross in fear, and seeing it now brilliantly shedding light-bestowing grace upon the faithful, amazed they stand and cry to you such words as these:
Rejoice, O Cross, guardian of the world;
Rejoice, the glory of the Church;
Rejoice, you that bountifully gush forth with healings;
Rejoice, you that enlighten the ends of the earth;
Rejoice, Wood fragrant with life, and treasury of wonders;
Rejoice, fitly-joined, thrice-blessed, and bestower of graces;
Rejoice, for you are the divine footstool;
Rejoice, for you were ordained for the worship of all;
Rejoice, bowl of nectar, full to the brim;
Rejoice, torch of the radiance above;
Rejoice, you through whom the creation is blessed;
Rejoice, you through whom the Creator is worshipped;
Rejoice, O Wood most blessed.
