How do we know that grace is sufficient for our weaknesses?

Believers often find themselves in need of grace due to the struggles of life and their own weaknesses. However, the assurance given in Scripture is that out of Christ's fullness, we continuously receive grace upon grace. Our resources may be drained, but we are privileged to access Christ's stock at any moment, ensuring we are never without help. The covenant made with Christ as our Mediator guarantees the provision of grace even to the weakest of believers, illustrating God's faithfulness and tender care.
