And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ. (Philippians 1:6) ..work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure. (Philippians 2:13)

And I will ask the Father, and he will give you another Helper, to be with you forever, (John 14:16, ESV)
