D&C 59

As the saints were commanded to gather, at first in Kirtland, the Lord said -

"...go to the Ohio; and there I will give unto you my law..." (Doctrine and Covenants Section 38:32)

Section 42 is much of the law that was given at that time. The Lord continued to give His law Kirtland and in Zion. Much of which He refered to as commandments. The Lord sees commandments as not a hindrance but as a great and positive thing with great promises saying -

"...they shall also be crowned with blessings from above, yea, and with commandments not a few, and with revelations in their time—they that are faithful and diligent before me." (Doctrine and Covenants Section 59:4)

The saints were told as they began to gather in Zion -

"For verily I say unto you, my law shall be kept on this land." (Doctrine and Covenants Section 58:19)

Behold, the laws which ye have received from my hand are the laws of the church, and in this light ye shall hold them forth. Behold, here is wisdom." (Doctrine and Covenants Section 58:23)

"Who am I that made man, saith the Lord, that will hold him guiltless that obeys not my commandments?
31 Who am I, saith the Lord, that have promised and have not fulfilled?
32 I command and men obey not; I revoke and they receive not the blessing.
33 Then they say in their hearts: This is not the work of the Lord, for his promises are not fulfilled. But wo unto such, for their reward lurketh beneath, and not from above." (Doctrine and Covenants Section 58:30 - 33)

In commentary on these verses we read -

"The Saints sometimes fail to do their duty and to keep the commandments of God. But they expect Him to make good to them the promises He has given to the faithful. If He does not, they complain. They neglect their prayers; they absent themselves from their meetings; they break the Word of Wisdom; they withhold their tithing; but when sickness comes and falls like a dark, terrifying shadow across their path, they expect immediate Divine interference in their behalf, through the administration of the Elders. If their expectations are not realized, they say, in a rebellious spirit, ‘His promises are not fulfilled.’ The reply of the Lord to that is, ‘Their reward lurketh beneath.’ They must look ‘beneath’ for their reward; they have no claim on heaven." (Smith and Sjodahl, Commentary, p. 340.)

In Zion, the Lord again reiterated His two greatest commandments -

"Wherefore, I give unto them a commandment, saying thus: Thou shalt love the Lord thy God with all thy heart, with all thy might, mind, and strength; and in the name of Jesus Christ thou shalt serve him.
6 Thou shalt love thy neighbor as thyself..." (Doctrine and Covenants Section 59:5 - 6)

With that, He addresses some important commandments that He may not have specifically mentioned previously -

"Thou shalt thank the Lord thy God in all things." (Doctrine and Covenants Section 59:7)

Adding -

"And in nothing doth man offend God, or against none is his wrath kindled, save those who confess not his hand in all things, and obey not his commandments." (Doctrine and Covenants Section 59:21)

And also -

"...that thou mayest more fully keep thyself unspotted from the world, thou shalt go to the house of prayer and offer up thy sacraments upon my holy day;
10 For verily this is a day appointed unto you to rest from your labors, and to pay thy devotions unto the Most High;
11 Nevertheless thy vows shall be offered up in righteousness on all days and at all times;
12 But remember that on this, the Lord's day, thou shalt offer thine oblations and thy sacraments unto the Most High, confessing thy sins unto thy brethren, and before the Lord.
13 And on this day thou shalt do none other thing, only let thy food be prepared with singleness of heart that thy fasting may be perfect, or, in other words, that thy joy may be full." (Doctrine and Covenants Section 59:9 - 13)

I note two footnotes as follows:

Oblation:

IE offerings, whether of time, talents, or means, in service of God and fellowman:

Fasting:

IE hungering and thirsting after righteousness;

With each of these commandments, the Lord provides great promises of blessings.
