Let us go back to that scripture in Ephesians 3, and we will complete Paul's thought where he mentioned the Family of God, because that thought was a prayer. In order to really fully understand this, it actually has to be connected with the very end thought of chapter 2 where he is talking about the body of Christ.
That is mind-boggling! That blows your mind! The whole purpose of everything that God is working out is that you (Put your name in there!) might be filled with all the fullness of Elohim! Boom! That blows your mind to think of that!
Is Elohim one? Yes! It is one institution. It is one family. It is one kingdom in which everybody agrees. It acts as one, and because it acts as one, even though it consists of many, it takes a singular verb. We have to change our thinking so that we understand that Elohim consists of more than one, even though individual members of Elohim acting in the name of our God, because they are part of the God family.
Jesus tried His hardest to help us to understand this by using family terminology: father, son, children, brothers, sisters. Brethren, is a family one, even though it has many members? Of course it is, and Elohim is that family.
Even in the Old Testament, brethren, there are two Yahwehs identified. Does that astound you? There is one verse that you are so familiar with. David said, The Lord said to my Lord, clearly showing that there are two in Elohim. But that is not the only place it appears. In Daniel 7 you will find, One like the Son of Man was brought before the Ancient of Days. There are other places as well where two Yahwehs are clearly shown.
I think most important of all for us right now is to get our minds straightened out to be in harmony with the Father and the Son. He tells us in this section right here that Christ may dwell - live, abide - in our heart. It means to settle down, as if in a house. Even there is a family reference, because that is where families live. They live in a house. He is telling us that we might be strong, to grasp, and to know by experience the vastness of Christ's love. This is something that cannot be adequately explained, and Paul never really attempted it. Of course, the purpose of all of Paul's request there is that we might be filled with the fullness of God.
