1. The trinity is the unification of the three members of the Godhead (God the Father, God the Son, and God the Holy Spirit). 2. I\'m not sure as to what kind of answer I\'m supposed to give (although technically I know there is no wrong answer, but yeah lol). I guess it affects my everyday life in that I communicate to God the Father, who is in control of all things, via God the Holy Spirit, who resides in me and comforts me and acts as my conscience, and this communication was made possible through God the Son, who shed His blood on the cross of Calvary and, in effect, washed away my sins when I accepted His love...on an everyday basis. Without the all three members of the Trinity, this one-on-one communication would not be possible, as I would be so covered with sin that He could not even look upon me.
