There are many issues with this. The biggest one is that it assumes that man has the authority to "not let [God] go." It is a blasphemous thing to say. We finite humans cannot contain the infinite God. He is immensely more powerful than we are. This reminds me of some Word of Faith teachings where people talk of commanding God. He is omnipotent, we are not. He is all-powerful, we are not. He does not submit to us, we submit to Him.
Another major issue is the attitude in which the prayer is said. As I had said, God does not submit to us. We submit to God. The prayer was not said with a submissive attitude, but with a domineering attitude. Think of a child who tries to tell a parent what that parent will do. Instead of the child asking, "Could you please give me a cookie?" the child says, "Give me a cookie or I won't let you leave the kitchen." The child has neither the authority or the ability to keep the parent in the kitchen. Anne wants the people in her sphere of influence blessed. Instead of praying, "Please bless these people," she says "I will not let you go until you bless those who are in my circle." In the same way, Anne has neither the authority nor the ability to keep God there (In fact, significantly less than even the child).
Read how Jesus said to pray.
"Pray then like this: 'Our Father in heaven, hallowed be your name. Your kingdom come, your will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from evil.'" (Matthew 6:9-13, ESV; Emphasis added)
Lotz did not pray "Your will be done." Instead, she prayed something to the effect of, "My will be done or else." This is not the proper attitude for prayer. What Psalmist assumed authority over God? What Apostle prayed a prayer with a threat to not let God go? The only prophet who attempted to put his will before God's spent three days in the belly of a fish before submitting to God. When you pray, do not pray as Lotz has suggested. Instead, use the model Jesus (God Himself) provided for us in Matthew 6.
