Again FB, Christ in the Father, and the Father in Christ, is a figure of speech. Just like a husband & wife become one, like David & Jonathan were one, like the Church is one, like the 3 Muskateers were one. It's an expression of unity in spirit. When a Christian has faith, the Holy Spirit resides in him. Not literally, but figuratively. The power is real, the residence is not.
Christ did not create anything, all was created for him, because he is the first-born of all creation. When the verse says that '...all things were created through him, or by him...' it means via, or, with Christ in mind. The universe was created for Christ, and we were created for him. God loved him that much.
God does not love God, that's ridiculous.
