How do we know Jesus' suffering at the cross was part of God's plan?

The suffering of Jesus at the cross was not an accident but part of God's divine plan. According to Acts 2:23, Jesus was 'delivered up according to the definite plan and foreknowledge of God.' This emphasizes that God was actively involved in the events leading to the crucifixion, establishing that the cross was a predetermined act of God for the salvation of His people. It was not merely the work of wicked men; God planned and executed His redemptive purpose through the suffering of His Son.
