2 Corinthians 5 & 6

Being and apostle and priesthood holder, Paul writes -

"...all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation..." (New Testament 2 Corinthians 5:18)

Where reconcile means to be in harmony with God and His will. Nephi wrote of the ministers of reconciliation -

"For we labor diligently to write, to persuade our children, and also our brethren, to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do." (Book of Mormon 2 Nephi 25:23)

The labor and work of His priesthood holders is to assist in this work of reconciliation. Even our Father in Heaven tells us -

"...this is my work and my glory—to bring to pass the immortality and eternal life of man." (Pearl of Great Price Moses 1:39)

The method of ministering the gospel of reconciliation, Paul teaches -

"Giving no offence in any thing, that the ministry be not blamed:
4 But in all things approving ourselves as the ministers of God, in much patience, in afflictions, in necessities, in distresses,
5 In stripes, in imprisonments, in tumults, in labours, in watchings, in fastings;
6 By pureness, by knowledge, by longsuffering, by kindness, by the Holy Ghost, by love unfeigned,
7 By the word of truth, by the power of God, by the armour of righteousness on the right hand and on the left." (New Testament 2 Corinthians 6:3 - 7)

Compare this to modern instruction to priesthood holders -

"Be patient in afflictions, revile not against those that revile..." (Doctrine and Covenants Section 31:9)

"No power or influence can or ought to be maintained by virtue of the priesthood, only by persuasion, by long-suffering, by gentleness and meekness, and by love unfeigned;
42 By kindness, and pure knowledge, which shall greatly enlarge the soul without hypocrisy, and without guile—" (Doctrine and Covenants Section 121:41 - 42)

"...lift up your hearts and rejoice, and gird up your loins, and take upon you my whole armor, that ye may be able to withstand the evil day, having done all, that ye may be able to stand.
16 Stand, therefore, having your loins girt about with truth, having on the breastplate of righteousness, and your feet shod with the preparation of the gospel of peace, which I have sent mine angels to commit unto you;
17 Taking the shield of faith wherewith ye shall be able to quench all the fiery darts of the wicked;
18 And take the helmet of salvation, and the sword of my Spirit, which I will pour out upon you, and my word which I reveal unto you..." (Doctrine and Covenants Section 27:15 - 18)

This is the ministry of reconciliation.
