Acts 9 & 10

As I have been reading the Acts of the Apostles, I noticed a distinct doctrine of the priesthood. When the priesthood is present on the earth, the Lord Omnipotent, who could easily do the work himself, seems to refrain and delegate to His presiding authorities to do his work on earth. As Cornelius -

"...feared God with all his house, which gave much alms to the people, and prayed to God alway.
3 He saw in a vision evidently about the ninth hour of the day an angel of God coming in to him, and saying unto him, Cornelius.
4 And when he looked on him, he was afraid, and said, What is it, Lord? And he said unto him, Thy prayers and thine alms are come up for a memorial before God.
5 And now send men to Joppa, and call for one Simon, whose surname is Peter:
6 He lodgeth with one Simon a tanner, whose house is by the sea side: he shall tell thee what thou oughtest to do." (New Testament Acts 10:2 - 6)

The angel could have easily told Cornelius what to do but instead, the Lord had Cornelius pursue His presiding priesthood leader, he who held the -

"...the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven." (New Testament Matthew 16:19)

...for further instructions. We see this same principle with Saul as he -

"...journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
4 And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
5 And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.
6 And he trembling and astonished said, Lord, what wilt thou have me to do? And the Lord said unto him, Arise, and go into the city, and it shall be told thee what thou must do." (New Testament Acts 9:3 - 6)

It was in Damascus that the Lord revealed in vision to Ananias -

"...Arise, and go into the street which is called Straight, and enquire in the house of Judas for one called Saul, of Tarsus: for, behold, he prayeth,
12 And hath seen in a vision a man named Ananias coming in, and putting his hand on him, that he might receive his sight." (New Testament Acts 9:11 - 12)

I believe Ananias was the presiding authority in Damascus at that time. And in obedience -

"...Ananias went his way, and entered into the house; and putting his hands on him said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Ghost." (New Testament Acts 9:17)

It seems in this manner that both individuals benefit and -

"...understand one another, and both are edified and rejoice together." (Doctrine and Covenants Section 50:22)

I all seems to support the doctrine -

"And these all, having obtained a good report through faith, received not the promise:
40 God having provided some better thing for us, that they without us should not be made perfect." (New Testament Hebrews 11:39 - 40)
