Prayer assumes the sovereignty of God. If God is not sovereign, we have no assurance that He is able to answer our prayers. Our prayers would become nothing more than wishes. But while God's sovereignty, along with his wisdom and love, is the foundation of our trust in Him, prayer is the expression of that trust.
Jerry BridgesIn order to trust God, we must always view our adverse circumstances through the eyes of faith, not of sense. And just as the faith of salvation comes through hearing the message of the gospel (Romans 10:17), so the faith to trust God in adversity comes through the Word of God alone. It is only in the Scriptures that we find an adequate view of God's relationship to and involvement in our painful circumstances. It is only from the Scriptures, applied to our hearts by the Holy Spirit, that we receive the grace to trust God in adversity.
