How do we know God's purpose is to finish the work of salvation?

The assurance of God's purpose to finish the work of salvation is rooted in His sovereign will. In Luke 24:49, Jesus indicates that He will send the promise of the Father, confirming that His work of redemption is not thwarted by human hatred or misunderstanding. Many witnesses to Christ’s crucifixion would later be transformed by the Holy Spirit's power during Pentecost, fulfilling Jesus's prayers for forgiveness and underscoring the certainty of redemption. As Romans 8:31-32 states, 'If God is for us, who can be against us?' We can rest assured that God’s plans will not be hindered by man, as He is committed to seeing His redemptive work completed through Christ.
