How do we know that God maintains our lot in life?

The assurance that God maintains our lot is found in the acknowledgment of His sovereignty and faithfulness. David says in Psalm 16:5-6, 'Thou maintainest my lot,' indicating that our paths and circumstances are guided by God's perfect will. This is foundational to the doctrine of sovereignty by grace, where we trust that God is actively involved in our lives, ensuring our spiritual and temporal needs are met. This maintaining work reassures us that nothing is outside of His control, and it imbues us with the confidence to lean fully on Him throughout our lives.
