On the yearly Day of Atonement, the high priest had to burn the incense before he could offer up the sacrifices. In that way, he made sure that he would have God’s approval when offering up the sacrifices. While on earth, Jesus had to do something important​—something more important than providing salvation for mankind—​before he could offer up his life in sacrifice. What was that? By living a life of integrity and loyalty, Jesus had to prepare the way for Jehovah to accept his sacrifice. In that way, Jesus would prove that doing things Jehovah’s way is the right way to live. Jesus would vindicate his Father’s sovereignty, or way of ruling. Throughout his earthly life, Jesus maintained perfect obedience to Jehovah’s righteous standards. No temptation or trial could weaken his desire to defend his Father’s way of ruling.​—Phil. 2:8. w19.11 21 ¶6-7
