In "Word Focus" Darrell Grim writes:
Bearing his cross (v. 17). It was the custom that four soldiers were detailed to each cross, and they were under the command of a centurion. The cross was usually carried by the one who would soon be nailed to it. In many cases his arms were tied to it. Normally they took the longest route and through the most crowded streets to attract the most public attention. This had a twofold purpose. First, it was a deterrent to others inclined to break the law. Second, it gave opportunity for anyone who had evidence in behalf of the condemned to come forth. Whether these customs were followed in the case of Christ’s crucifixion is unknown.
"Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God" (Hebrews 12:2, KJV).
Discussion: As followers we are to take up our cross daily and follow Jesus. What does this say then about the "shame" we may endure as a result of carrying our cross for Jesus?
