Galatians 6:7-9 (KJV)
7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
Our work in this verses begin with a season of sowing and ended with a season of reaping. Those who soweth to the Spirit shall of the Spirit reap life everlasting.
Ephesians 1:15-23 (KJV)
15 Wherefore I also, after I heard of your faith in the Lord Jesus, and love unto all the saints,
16 Cease not to give thanks for you, making mention of you in my prayers;
17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:
18 The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,
19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power,
20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,
21 Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come:
22 And hath put all things under his feet, and gave him to be the head over all things to the church,
23 Which is his body, the fulness of him that filleth all in all.
It seems to me that Jesus have all power over all principalities in this world and the world to come according to verse 21. And He shares that power with the Church according to verse 22 and 23. So, I think we are the rulers of this world and the world to come with Jesus as our head ruler.
