What is the meaning of 'fallen from grace'?

In Galatians, when Paul speaks of falling from grace, he is addressing the misconception that one can achieve righteousness through adherence to the law. The moment individuals place their trust in the law to justify them, they disconnect from the grace offered through faith in Christ. Thus, the phrase signifies the peril of relying on one's own works instead of resting in Christ’s perfect sacrifice. True believers, however, are kept by God's power and secured in their relationship with Him through faith, affirming that falling from grace is a condition of faith, not a loss of salvation.
