John 3:8 "The wind blows where it chooses, and you hear the sound of it, but can't tell where it came from, and where its going: so is every one that is born of the Spirit."
What an interesting statement. Christ is saying that the acts and deeds of the righteous won't be understandable: They won't fit in with any known pattern. It states that such people will appear inconsistent. Christ taught this same thing when challenged in regard his apostles picking corn upon the sabbath. Remember that God was so fussy about resting on the sabbath that when Israel were collecting manna in the wilderness they weren't even allowed to go out and just collect it on the sabbath. So how would he feel about picking corn? Yet Christ put this off by quoting a concept of flexability due to circumstance.
Matt 12:3-4 "But he said unto them, Have ye not read what David did, when he was an hungred, and they that were with him; How he entered into the house of God, and did eat the showbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests?"
The gospel does give a freedom. But how should this freedom be used? This built in flexability can be used for our destruction if we are not using the Spirit. Which gets back to the original quote. It is only those born of the Spirit (those who no longer sin - 1 Jn 5:18) that have obtained this ability to be guided purely by the Spirit. It requires a person to be purged of evil intent - no lust, anger against people, greed or pride. How can the Spirit be with us when we have such things in our heart. The constant companionship of the Spirit must be acheived through our righteous hearts. The Spirit has to feel good about being with us. But if we plan on eternal life we must acheive this relationship.
D&C 45:57 "For they that are wise and have received the truth, and have taken the Holy Spirit for their guide, and have not been deceived--verily I say unto you, they shall not be hewn down and cast into the fire, but shall abide the day."
This is saying that to be alright in the judgement we must have become totally guided by the Spirit. What Christ has said, in my original quote, is that the actions of such a person may not entirely fit in with some convention or normal set of rules. It will require the Spirit to understand such a person's actions. A good lesson not to judge others by the hearing of the ears or the seeing of the eyes (refer Isa 11:3).
