Though they acted in sinful ignorance in killing the Messiah, they were not beyond God's grace. As the prophets foretold, it was God's will that His servant Jesus suffer to accomplish the salvation of His people. Now, if they would believe, they could receive forgiveness, they could be prepared for Christ's return, and they would receive the promised covenant blessings.
