How do we know God's keeping grace is true?

The doctrine of God's keeping grace reflects His promise to protect and sustain believers in their faith. This assurance is grounded in scriptures such as 2 Timothy 2:13, which states that even if we are unfaithful, God remains faithful and cannot deny Himself. This truth reassures us that our shortcomings do not negate God's commitment to uphold us. Furthermore, Christ promises that no one can snatch His sheep from His hand (John 10:28), illustrating the eternal security of the believer, anchored in the efficacy of Christ's atoning work and God's immutable grace.
