How do we know God's sovereignty in prayer?

Daniel's prayer illustrates a profound understanding of God's sovereignty. While he recognized that God had determined the 70 years of captivity, he did not view this as a reason to refrain from prayer. Instead, he saw it as encouragement to pray. This reveals a key theological principle: God's sovereignty includes the means of prayer by which He works out His divine plan. We understand that prayer does not change God's will but is part of the ordained process by which believers participate in God's purposes.
