Jeremiah 32:39

Jeremiah 32:39 And I will give them one heart and one way, to fear Me all the days, for their own good and for the good of their children after them.

We, the chosen people of God, should all have one heart and one way. We should have one heart to love God, to seek God, to live God, and to be constituted with God. This means that we love to be the expression of God. 

The one way is just the Triune God. As the Body of Christ, we should take the way of the inner law, which is the Triune God with His divine capacity.
