A couple things in your question kind of popped out at me.
One Thing: Stewardship
One thing concerns your first point. The word you didn't mention (but alluded to) is stewardship, a concept which is taught throughout Scripture in many and varied ways. A steward (an old-fashioned term for a servant, or employee, who is in charge of some aspect of his boss's business) is accountable to his boss for what he does with the boss's stuff, be it real estate or any other asset which has been entrusted to the steward.
The clear teaching of Scripture is that you and I have nothing which was not given to us (1 Corinthians 4:7). Put positively, all we possess is a gift from God. Whether our genetic makeup, our talents and spiritual gift-mix, our possessions, or the very next breath we take, all these things and more are gracious gifts from God (see Acts 17:24-28, especially v.28).
To be sure, God has given us all things richly to enjoy (1 Timothy 6:17), but ultimately, accountability will always be an aspect of who we are and what God has entrusted to us. Moreover, God expects and deserves faithfulness of his stewards. Even if he seems to have given us what from our perspective is very little, he nevertheless expects and deserves a return on his investment. Not to put too fine a point on it, Jesus bought us outright at the cross. He demonstrated his love for us at Calvary despite our being sinful, rebellious, lost, condemned, disobedient, unrighteous, helpless, and objects of his wrath (Romans 5:1-9). We therefore owe him a debt of love and gratitude we can never fully repay.
Another Thing: God's Sovereignty
Another thing concerns your fourth point about God ultimately being in charge of all that is, and God being free to do whatever he pleases with what is his. The term theologians use in this regard is sovereignty. While there is tremendous disagreement among Christians as to how God's sovereignty is exercised here on earth, we can all agree God is in fact sovereign. No authority is higher than his, no one's will can ultimately triumph over his will, and no one (no person, power, or malignant influence) can prevent his ultimate victory over sin, death, and hell. Toward that end, all of humanity is headed, and while God's timetable for having the last word is unclear to us, we nevertheless know it will be spoken:
The kingdom of the world has become the kingdom of our Lord and of His Christ; and He will reign forever and ever (Revelation 11:15b NASB Updated).
All this to say, if God's children truly want his will to be done "on earth as it is in heaven," then the duty incumbent upon us is to accomplish his will in his way. His way involves our complete trust in his strength, power, and ability. Yes, we can attempt to do his will in our own strength--in the strength of our flesh, but at the Judgment Seat of Christ those attempts will be burned up and we will suffer loss.
On the other hand, those things we do in the strength and love which God himself provides will survive the fire of Christ's judgment and be rewarded handsomely (see 2 Corinthians 5:9-11). Moreover, God alone will be glorified both now and then, for his glory is really the ultimate good. Yes, we his children are blessed when we do his will and do it in his way, but we do it all for God's glory, not ours:
For from Him and through Him and to Him are all things. To Him be the glory forever. Amen (Romans 11:36).
By the way, notice the verse which follows Romans 11:36; namely,
Therefore, I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship (12:1).
In light of God's mercies toward us sinners, we can do nothing less than give back to God everything he has entrusted to us, plus interest (see Matthew 25:1 ff.)!
