We celebrate the gift and work of the Holy Spirit.  After Jesus' ascension into heaven, the promised Holy Spirit was gifted to the disciples.  It is through God's Holy Spirit is twofold; (1) we recognize that we are broken and in need of a savior for we are not perfect, nor can we hope to live up to God's righteous standards because of sin in our very being and (2) it is the Holy Spirit who then opens Scripture teaching us about the Savior of all, by whose death and resurrection we are no longer judged unrighteous and guilty before God because of Christ's sacrifice.  In fact, we can sum up the work of the Holy Spirit in this way: Earth, Water, Wind Fire.  We, made from the earth and to return to the earth, were washed with the water of salvation (Baptism), in which God' Spirit brings us life and salvation.  This is not merely a one-time job for He is constantly with us in the "winds of war" against sin and temptation in this world.  He is on the battlefield with us, when we cry out for forgiveness, when we seek strength and fortitude against violence, selfishness.  In this way, the Spirit is like fire.  Struggling with our sinfulness in this world, desiring to live God-pleasing lives and free to do so, our faith is tested and purified and tested as gold  ("fire" and "pure" share a common Latin root).  His work is not complete until we are finally with our Lord in Heaven.
