God Has A Plan, And Hold Us Accountable, At The Same Time

Read Joseph's words in Genesis 50:20. First he says that his brothers' intended to harm him. That's man's agency and accountability. They themselves did it, and there was no excuse for what they did. Then Joseph says God intended for their evil intention to save their whole family. By selling Joseph to slave-traders, Joseph ended up years later as prime minister of Egypt, and had the legal and political authority to welcome in his entire family. That's God's sovereignty. 

Wiping out human agency and responsibility under the guise of teaching God's sovereignty is always wrong. Wiping out God's supreme sovereignty in the name of human free-will and responsibility is also always wrong. Both realities are true, at the same time, all the time.
