How do we know Jesus' suffering in the garden was real?

The reality of Jesus' suffering in the Garden of Gethsemane can be seen through the vivid descriptions in the Gospels, particularly in Luke 22:44, where it is noted that 'being in agony, He prayed more earnestly, and His sweat was as it were great drops of blood falling down to the ground.' This illustrates the intense turmoil and emotional distress He faced as He approached the cross. Furthermore, His expression of sorrow indicates His deep, human experience of anguish, fully acknowledging the weight of sin being placed upon Him. This moment shows that His suffering was not merely physical but profoundly spiritual, as He was bearing the sins of His people, which would result in His atoning sacrifice.
