How do we know that Jesus' death was purposeful?

Jesus was aware of His impending death, which serves as a parallel to Moses' own knowledge of his death. The scriptures indicate that Jesus was the Lamb slain before the foundation of the world, affirming that His death was not a mistake but a divine orchestration for our redemption (Revelation 13:8). Throughout His ministry, He spoke of His mission to lay down His life for His sheep and expressed no reluctance in fulfilling this role, as seen in Isaiah 50:5 where He set His face like a flint towards His sacrifice. This intended purpose highlights the certainty and assurance of salvation for His people, illustrating that His death was both necessary and sufficient for our redemption.
