How do we know Christ's work on the cross is enough for salvation?

The effectiveness of Christ's work on the cross is rooted in its fulfillment of God's justice. According to Romans 3:26, God is both just and the justifier of those who have faith in Jesus. His sacrificial death paid the penalty for sin, allowing God to be gracious to His people. The preacher emphasizes that through Christ's resurrection, He provided the means for believers to be accepted before God, as all that is needed for salvation is found in Him. Furthermore, Ephesians 2:8-9 confirms that salvation is a gift, not dependent on works, highlighting the completeness of Christ's redemptive act.
