I would prefer to say that there is no "balance" in the correct understanding of the sovereignty of God. There are merely multiple issues in the cascade of the theology.
The word "balance" suggests that two different ideas are being pitted against each other. This is the wrong approach, since the doctrine of man's responsible free agency is subsumed under the high doctrine of predestination.
Spurgeon pointed out this fact to a lady who asked "How can you reconcile predestination and human responsibility?"
He answered by pointing out that her very question betrayed a misunderstanding of the overall issues in the sovereignty of God. He said that her question is like asking how we can reconcile a man and a woman who are madly in love with each other.
His point is that they don't need to be reconciled. They fit together beautifully. By the same token, balance is not really at issue in the picture of predestination and free agency.
