Philippians 2:12-13

Therefore, my dear ones, as you have always obeyed [my suggestions], so now, not only [with the enthusiasm you would show] in my presence but much more because I am absent, work out (cultivate, carry out to the goal, and fully complete) your own salvation with reverence and awe and trembling (self-distrust, with serious caution, tenderness of conscience, watchfulness against temptation, timidly shrinking from whatever might offend God and discredit the name of Christ). [Not in your own strength] for it is God Who is all the while effectually at work in you [energizing and creating in you the power and desire], both to will and to work for His good pleasure and satisfaction and delight.
