What does it mean to have a heart fixed on God?

A fixed heart is one that is resolutely committed to God and His purposes. In Psalm 57:7, the psalmist expresses that his heart is prepared and fixed upon God, indicating a deep-seated trust and reliance on Him. This steadfastness results from being grounded in the truths of Scripture and experiencing God's mercy and grace. The believer's heart, through the work of the Holy Spirit, is changed to delight in God, worshipping Him wholeheartedly and eagerly awaiting His intervention in our lives.
