How do we know we can have rest in Christ?

The concept of rest in Christ is deeply rooted in the understanding that salvation and peace come through Him alone. As mentioned in Hebrews 4, entering God's rest is a promise extended to believers; however, it requires faith. Just as the Israelites failed to enter the promised land due to unbelief, Christians are warned not to harden their hearts against the gospel. The rest provided by Christ is a perfect reconciliation between sinners and God, grounded in the finished work of the cross. This rest is both a present reality for believers and a promise of eternal peace with God.
