Martin Luther,
Epistle Sermons, Vol. 2: Epiphany…
“ Obedience to the Father moved him. Here Paul with one word unlocks heaven and permits us to look into the unfathomable abyss of divine majesty and to behold the ineffable love of the Fatherly heart toward us—his gracious will for us. He shows us how from eternity it has been God's pleasure that Christ, the glorious one who has wrought all this, should do it for us. What human heart would not melt at the joy-inspiring thought? Who would not love, praise and thank God and in return for his goodness, not only be ready to serve the world, but gladly to embrace the extremity of humility? ”
