Does "For thine is the kingdom, and the power, and the glory" mean...

For thine is the kingdom,
and the power, and the glory,
A newer version...
For the kingdom, the power, and the glory are yours
now and for ever.
Basically it means...
For heaven, the power of god and the glory of god are yours...

The restatement of the prayer, as found in Luke 11:2-4, reads: “Father, hallowed be thy name. Thy kingdom come. Give us each day our daily bread; and forgive us our sins, for we ourselves forgive every one who is indebted to us; and lead us not into temptation.”—Revised Standard Version.
Contradiction was brought into this prayer when some religious copier of the Holy Scriptures added to the prayer as given in the Sermon on the Mount the following words: “For thine is the kingdom, and the power, and the glory, for ever. Amen.” (Matt. 6:13, Authorized Version, Martin Luther German Version) As a result hundreds of millions of religious people in Christendom have for centuries recited the prayer with the addition of those unauthorized words as a conclusion or doxology. Seemingly they have never stopped to think of how at the beginning of the prayer they could recite the words “Thy kingdom come” and then in the conclusion of their prayer say: “Thine is the kingdom.” If the kingdom was already God’s, why should they pray in the same prayer: “Thy kingdom come”?
This shows the foolishness of adding something to God’s inspired Word with the idea of trying to improve it or fill it out. Well did Proverbs 30:5, 6 warn against this, saying: “Every saying of God is refined. . . . Add nothing to his words, that he may not reprove you, and that you may not have to be proved a liar.” Certainly in Jesus’ day God’s kingdom had not come.
