Romans 8:29, 31:

For those whom he foreknew he also predestined to be conformed to the image of his Son…  What then shall we say to these things? If God is for us, who can be against us?

If God is “for me” in the process of my becoming holy like Jesus, then despite all evidence to the contrary, despite all contrary influences from within and without, despite my own reluctance and sluggishness and halfheartedness, he will bring it about.
