"Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession[or confession], Christ Jesus." (Hebrews 3:1)
Very few believers today understand the mystery of the apostleship and priesthood of Jesus. We think that an apostle is some kind of supersaint. But "apostle" actually means "sent one." So, Jesus has been sent from God to do something for us.
He's been sent to serve as our High Priest. Again, many believers don't have the first idea what a high priest does. They picture a person walking around in strange clothes performing religious rituals.
In reality, a high priest is much more than that. He is one who is authorized to administer, to execute, to implement and to carry into effect. Now, you may wonder what it is that Jesus is authorized to administer, execute, or carry out on your behalf. Hebrews 3:1 says that Jesus is the High Priest of our confession. He's been sent to put into effect, to execute, to carry out the words that you say.
But have you been speaking what you feel, instead of speaking words of faith? If, for example, you're speaking sickness, what's He going to do with that? He's not High Priest over sickness. He can't execute that. If you're saying, "I'm so weak, I'm so tired," He can't carry that out. The Bible says, "Let the weak say, I am strong!" The minute you say that, Jesus can administer STRENGTH.
Jesus is not going to administer sickness or disease or poverty or sin. He's defeated all that. He is High Priest over deliverance and righteousness and freedom.
Consider that. Then as you come before Jesus, don't speak words of defeat. Speak words He can implement-- words of victory. That's what He's been ordained by God to bring to pass in your life.
