A,B. When we live a life that models the one Christ lived while on earth, we honor God: a life of grace, love, compassion, mercy, kindness, self-control, deep respect for his father. This makes us beyond reproach by the onlookers. The words that we speak should also honour God; abstaining from filthy communication and speaking of his name with overfamiliarilty.
C. We hallow the father when we pray by first of all approaching him as he has revealed himself to be, a father. From that place of relational intimacy, there should also be deep respect as we commune/speak with him.
