Why should Christians trust in an immutable God?

Trusting in an immutable God is fundamental for Christians due to the certainty it provides regarding salvation and divine grace. Jesus’ promise that no one can snatch His sheep from His hand (John 10:28-29) illustrates that His protective care and commitment do not fluctuate. This assurance allows believers to rest confidently in their relationship with Him, knowing that His promises are as firm as His character. Furthermore, since God's merciful nature is everlasting, believers are encouraged to rely on His grace, especially during trials, as it remains constant and sufficient despite their fluctuating circumstances.
