Gratefulness has three steps: not missing the opportunity, appreciating the opportunity, and using or enjoying the opportunity. By this method we come fully alive, full of joy, which is what we are all longing for.
Advent is a season to ponder "all these things" in our hearts:
Thomas Merton calls us all to contemplation in his book of Contemplative Prayer ...
" ... the most important need in the world today is the inner truth nourished by the Spirit of contemplation -- the praise and love of God, the longing for the coming of Christ, the thirst for the manifestation of God's glory, truth and justice -- the Kingdom of God in the world."
