11 If perfection could have been attained through the Levitical priesthood—and indeed the law given to the people established that priesthood—why was there still need for another priest to come, one in the order of Melchizedek, not in the order of Aaron? 12 For when the priesthood is changed, the law must be changed also. 13 He of whom these things are said belonged to a different tribe,and no one from that tribe has ever served at the altar. 14 For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. — Hebrews 11:7-14 NIV
Perfection could never come through man. The law that established a human priesthood was given to show us that we could never live up to the standard that God required — perfection. Knowing this, the Trinity, long before the foundations of the earth were laid, set in motion a plan for our redemption. A new priesthood wherein the new Priest would not come from the tribe of the Levites, but rather through the tribe of Judah. This Priest would not be ordained by man but by the Creator of heaven and earth, God Himself. This Priest would lay aside his royal garments and become like man in every respect. He would be tempted and suffer persecution but still remain obedient, even unto death on a cross. He was and still is our Shepherd and our Savior. He has every right to expect us to allow Him to be Lord of our lives. We do that by following His example under the leadership of the Holy Spirit. Our allegiance is changed completely. Once we walked in darkness on a path of constant chaos that led only to eternal death. Now, we walk in the light on a path of peace that leads to life everlasting in our Father’s house. Every day, from the day we accept Christ as our Savior until we arrive in heaven, we are on our way, we are going home.
5 Thomas said to him, “Lord, we don’t know where you are going, so how can we know the way?” 6 Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me. 7 If you really know me, you will know my Father as well. From now on, you do know him and have seen him.”— John 14:5-7 NIV
