Why is it important to understand that salvation is by grace?

It is crucial to grasp that salvation is by grace because this truth frees believers from the bondage of legalism and self-reliance. Romans 11:6 articulates that if it is by grace, it cannot be works, for then grace would no longer be grace. This essential understanding enables believers to rest in Christ's finished work rather than striving in their own strength, which can lead to despair and guilt. Knowing that our redemption is based solely on Christ's sacrifice assures us that our relationship with God is secure and not dependent on fluctuating human performance.
