What is the context?
This verse belongs to the crucifixion account in Luke 23:32–38. Jesus has been placed between two criminals, and His garments are being divided. He addresses the Father in a prayer for the forgiveness of those who do not know what they are doing. (Read the surrounding passage)
Their ignorance does not turn the crucifixion into a good act. It is the condition Jesus brings before the Father as He seeks mercy for them. The verse places His prayer beside the dividing of His clothing, holding His intercession and their actions together.
The BSB includes the prayer in its main text and notes that some manuscripts omit it. The whole verse is retained here, including the dividing of the garments. (BSB text and footnote)
How is this passage commonly understood?
Christian readings commonly understand the prayer as mercy toward those responsible for Jesus’ suffering. Wesley emphasizes His concern for their salvation, and the Catholic Catechism connects His prayer and the people’s ignorance while rejecting collective blame against Jews as a whole or in later generations. (Wesley on Luke 23:34; Catechism §597)
Where does this fit in God's plan?
Isaiah’s Servant bears the sin of many and intercedes for wrongdoers. Jesus’ prayer is a supported parallel with that description: His saving work includes seeking mercy for people who are doing wrong, rather than only displaying their guilt. (Isaiah 53:11–12)
Jesus has also taught His followers to love their enemies and pray for those who mistreat them. Acts records Stephen praying that the sin of his killers not be held against them. Stephen’s prayer is a clear parallel with Jesus’ example, showing how the mercy seen at the cross shapes the people who follow Him. (Luke 6:27–36; Acts 7:54–60)
What is our position?
Our study What Does Prayer Look Like? reads Jesus’ prayer for forgiveness as intercession entrusted to the Father. Jesus brings those responsible for His death before God in mercy. The lesson we draw is to pray for others while leaving the outcome with the Father.
