1. God will use you.
Oh, so we're nothing more than pawns on a chessboard. Slaves are used. Prostitutes are used. Children are not. We're not slaves or prostitutes, we're children of God. Love does not use others.
Ask Joseph if God used his evil brothers. We are slaves, either to satan or God, either to unrighteousness or righteousness, to either sin or to Christ. Once you get over the idol of free will, you're happy to be a slave to Christ, and desire to be a slave to righteouness, and free will becomes miserable.
2. Love your spouse more than God
The only way to love God more than your spouse is to love God through your spouse. Jesus says as much as we do unto others, we do unto him, and vice versa. If you think you need to have private prayer time when your spouse needs help with the kids or something else, that’s not prayer. That’s sin.
I agree in that we should love God more than our spouses, however I disagree with the notion of using a spouse as a medium to love God. Although I do agree that part of loving God can done through loving others if we are loving as the Spirit wills in God pleasing and honoring ways as Christ Himself loves. As for prayer time per above, it's not sin, it's called sacrifice and the door swings both ways in a good healthy relationship.
3. God can't bless you until you get that sin out of your life.
Do you ever drive 5 miles over the speed limit? Is that a sin? Yes it is, you're breaking the law. You sin so many times in one day you don't even realize it.
I agree in that God blesses whomever He wants to bless, but what man considers blessing from God, may turn out to be his own undoing. What will it profit a man if he gains the whole world but looses his soul? We see it happen time and time again, people who gain power, wealth, and fame, only to be ruined by it. Now spiritual blessings from God, the riches of Christ, they are gifts from God for Him to give as He pleases, and since all Christians deal with sins throughout the course of their life, it would be crazy nonsense to think God cannot bless us until we take the initiative, in fact, God blessed us while we were yet sinners, He loved us first, not because of anything in us worth loving, but because of His mercy His pleasure and for His glory. I'll not argue whether breaking a man made law is a sin or not, that's a discussion in and of itself.
4. I'm committed to Christ
That's like saying you're committed to never cheat on your spouse. But what that really means is, "Though I want to cheat on you, I won't do it 'cause I'm committed." Commitment isn't even an issue if you love God or your spouse or anyone.
I think the issue is a bit more complicated. People get married and make commitments in their vows without any intention of ever cheating, they may be married for many years, faithfully committed, until one day long after the honeymoon and feelings are not quite the same, temptation comes at an opportune time. Being committed to Christ, basically means following Him as Lord and master. Many of us have discovered after years of following Him, that Christ is faithful and we are not. Christ is a Covenant keeper, while we are Covenant breakers. It's not as though the intention from the start is to be unfaithful, but the valley's of life, the ways of the world, have a way of dragging the most Godly of Christians down. We are only as committed as Christ is committed to us, and He is faithful, so all glory and boasting is in Christ, not in our performance or lack of.
5. Lord, I want to do whatever pleases you. I want to decrease; you must increase.
Imagine if you married someone who spoke like that. "I want to do whatever you want to do dear. It's not about me, it's all about you." That would be fun for about a week. "I just want to be used by you. I just want others to know how much I am committed to you." Then your heart would break.
Those desires are not natural, they are from God, in ourselves we desire to please ourselves and look out for number one. I am puzzled by what you're arguing against on this point, because we are called to "take up our cross", the greatest example of prayer in Scripture has these words: "Thy will be done". If a Christian does not desire to do whatever pleases God, that should give pause, it should not be consider faith, because without faith it is impossible to please God.
6. God has unfinished business in my life.
What were some of Jesus's last words? "It is finished." As far as he's concerned, there's no past, present, or future. For him, it's already done.
Except the Spirit of God in a believer works through believers to do the will of God and that may be part of a bigger plan which we are not aware of. Think for just a minute about everything that had to happen for you to be saved. Are these variables, causes and effects leading to your salvation without importance or not necessary? Never mind the command to go ye to all nations and baptize... Our lives are unfinished until the appointed time God has decided, which all part of His greatest plan for His creation. Jesus last words have to do with salvation accomplished, but the Scriptures do not end there, neither did the unfolding of salvation of God's people throughout history in time. So far as the knowledge of God in eternity is concerned, everything was finished before anything ever started. So there you go, if you are still breathing, God is not finished with you here on earth.
7. We will be careful to give you all the glory God.
God actually wants to share his glory. Moses' face was shining with glory when he came down from Sinai. Paul says that if we share in Jesus's sufferings, we will share in his glory.
God did not create man to worship man period. Romans chapter 1 makes that abundantly clear. I would be careful about that notion of sharing the Glory of God as though God were our glory tree to shake some glory from to share with others.
