If the last post did not make the matter clear enough, the Lord emphasizes here the formula He has provided in this ordinance:
-"Always observe to do." It is to be done, and when it is done it is to be done in an "observant" way.
-"Even as I have done." His example is intended to clarify and define the manner the ordinance is to be observed. He regulates it by what He has done.
-"Even as I have broken bread and blessed it." The manner, the process, the gestures of breaking it first and then blessing it second, are to be followed exactly.
-"And given it unto you." When it is broken, then blessed, those who qualify by having repented and been baptized receive it as a gift or token from Christ. It is His body.
Now the Lord clarifies in explanation what He has earlier clarified in the blessing: This is to be done "in remembrance of [His] body." It is through His body that He, the living sacrifice, shows us the way. A loving God has died for us. His body is a testimony of life, obedience, sacrifice, cruelty, forgiveness, death, resurrection, immortality, power and glory. When you remember His life you should remember all that is associated with it.
Here the Lord reminds the Nephites they are to remember the body "which [He] has shown unto [them]." The sacred embrace and ceremony of recognition (a term I coined in The Second Comforter), should return to the mind of those present whenever they received the bread again. The Lord could give no greater testimony of what He had done, who He was, and how He served them than by showing to them His risen body still bearing the marks of crucifixion.
The act is intended to be a "testimony unto the Father that ye do always remember [Him]." The act of testifying is not composed merely of the act of eating the bread. To actually testify to the Father you must:
2. Be baptized
3. Receive the bread after it has been properly blessed with power
4. Remember His body and the ten things symbolized through it
This is the acceptable sacrifice the Father will receive as a "testimony" of Christ.
Should you perform this, then you will receive power to "have [His] Spirit to be with you."
These are simple steps. They are possible to be performed. When they are, the Father receives the act as a testimony before Him of the truth that you do always remember His Son. It will be recorded in heaven, and will be a witness for your salvation in the Day of Judgment.
These are solemn things. It is clear enough that we accomplish these things. But it is not clear how often they are performed, even in a church, which at one time, conducted a ceremony twice each Sunday, and today conducts it once each Sunday.
It is interesting the Lord should give us language that makes "observing to do" and "as He has done" a required part of the process. Those words are probably best when viewed in their clearest meaning, and accomplished with exactitude. Though He measures our hearts, when instructions are given in simplicity, one fair measure of the heart is how closely we follow the instruction.
Since the result is to have His Spirit to be with you, it should be a simple matter to determine by reflection if you have His Spirit as your companion. If you can feel that He is always with you, then you have an acceptable testimony to the Father. If you do not, then perhaps you should revisit the steps He has provided to see what you might improve. There is a law irrevocably decreed before the foundation of the world upon which all blessings are predicated. And when we receive any blessing from the Lord, it is by obedience to the law upon which the blessing is provided. Therefore, it makes sense that you can determine the extent to which you have followed the formula by the result promised. Having Christ's Spirit to be with you is significant enough proof that you should know the truth of the matter. Since you know the means by which to judge, see that you judge the matter correctly.
