We cannot begin in this life to comprehend the fullness of what that means. Indeed, eternity is too short for us to begin to know how great are the riches of glory that God has reserved for us and will forever cause to abound to us. In addition to our having a knowledge of the greatness of the salvation that God has given us in Christ, it is also essential that we know that His power is working in us to accomplish that salvation. The omnipotence of God is devoted to securing our hope. Paul goes on to explain that the power of God working in us is the same power by which Christ was raised from the dead.
Resurrection power is the miraculous power of creation.
All three points are brought together here. The power that is working in us is the same power that brought our Lord Jesus to glory. God will do in us as He did in Christ, for we are His people, one with Him. God worked in Christ so that He realized the hope of His calling and was given eternal glory with God. God is now also working in us in the same manner.
