Why is relying on God's grace important for Christians?

Dependence on God's grace is pivotal for Christians as it signifies recognition of our inherent weakness and the need for divine support. The psalmist's plea, 'Hold me up and I shall be safe,' illustrates the necessity of casting our reliance on God's strength instead of our own. Without this reliance, believers risk falling into spiritual vulnerability against temptations and trials. God's grace not only offers a foundation of security but also strengthens and protects believers from the evil one, enabling them to stand firm in their faith.
