Pharaoh's daughter

Commenting on the role played by Pharaoh's daughter in the raising and forming of Moses (and, so, in the redemption of Israel) Peter Enns writes,

What is our proper posture toward an unbeliever? There is more than one biblical model. The model of "opposition" is certainly well known and has ample biblical precedent. This model, however, is not deserving of universal application. We share with others the love of Christ, who was a friend to sinners. In doing so, we bring the good news to them in many different ways, which is something that God's people are called to do. But do not be surprised if in the process the Lord uses these same people to change you. Our neighbors, coworkers, and relatives are not so much projects to be won, notches on our salvation belt, but people who are created in God's image and whose lives are in God's hands. They, too, may be his instruments for purposes we cannot fathom. It is his will to employ many facets of his creation for his sake and for his glory. (Exodus, NIVAC, p.76)
