Who Should Be a Part of Whose Life?

I've been told many times (usually in a homily) that God needs to be part of my life.  It doesn't quite sound right.  Kinda like, "I have the active part of my life, the intellectual part of my life, the social part of my life, and the God part of my life."  I want what the saints had:  to be completely devoted to God.  And not just that.  To be in Christ. Not even just to belong to Him, but to be taken up into His Life.  To be part of His Life.  That's better:  We should strive to be part of God's Life, rather than to make Him part of ours.
