God has an eternal purpose and has worked out a plan to fulfill this purpose. You and I are in it!

God has one Purpose.

God wants to bring more sons to glory. For it became Him, for Whom are all things, and by Whom are all things, in bringing many sons unto glory – Heb 2:10. He wanted to expand His family. His sons would be from humans and would consist of a people who would gladly submit to His will and live with Him for ever sharing His glory. They would bear His image and be in His likeness. They are born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. – John 1:13. Women=Men. No difference.

In His purpose, God desires His would-be sons be gathered together in His first-begotten Son, the Lord Christ Jesus. That in the dispensation of the fulness of times He might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in Him. – Eph 1:10. But as many as received Him, to them gave He power to become the sons of God, even to them that believe on His name. – John 1:12.

As His purpose is being accomplished, God wanted to exhibit His manifold wisdom to the spiritual principalities and powers – good and evil. He is now showing them the riches of His mercy, His grace, His love and His glory, apart from the riches of His power, in the lives of His believers. To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God – Eph 3:10. And that He might make known the riches of His glory on the vessels of mercy, which He had afore prepared unto glory. – Rom 9:23.
