How do we know Jesus' crucifixion was God's plan?

The events leading to Jesus’ crucifixion, particularly the trial before Pilate, underline the sovereignty of God’s plan in salvation history. Acts 2:23 mentions that Jesus was ‘delivered up by the predetermined plan and foreknowledge of God.’ This shows that while human agency is involved, God's sovereign purposes are fulfilled through these actions. Peter’s proclamation at Pentecost reminds us that although the Jews acted wickedly in their decision to condemn Jesus, it was accomplished according to God's eternal counsel. This reflects the Reformed understanding that God's grace is operative even amidst human decision-making, illustrating His authority over all events.
