Truth is eternal, meaning progressively expanding forever as you learn more of it. When you are obedient to your light, you receive more: your level of both awareness of reality and understanding of right and wrong increase:
23 And that which doth not edify is not of God, and is darkness.
24 That which is of God is light; and he that receiveth light, and <u>continueth in God, receiveth more light;</u> and that light groweth brighter and brighter until the perfect day.
25 And again, verily I say unto you, and I say it that you may know the truth, that you may chase darkness from among you; (D&C 50)
26 The Spirit of truth is of God. I am the Spirit of truth, and John bore record of me, saying: He received a fulness of truth, yea, even of all truth;
27 And no man receiveth a fulness unless he keepeth his commandments.
28 He that keepeth his commandments receiveth truth and light, <u>until he is glorified in truth and knoweth all things. (D&C 93)</u>
Awareness is like a flooded bank. As you acquire truth, the water recedes, and you see things about yourself, the world, and the gospel that you had never before imagined. God graciously hides all but the minimum amount of truth from us at first so that we are not overwhelmed by being exposed to what we are not prepared to see. As soon as and as often as we obey what we have, he reveals more. Eventually, when our faith and trust in him becomes unshaken, we begin obeying what he reveals immediately when he reveals it. Though this does not mean he reveals all remaining truth in this sphere to us at once, it does mean that he can do it faster than before, because we no longer need to follow the alienation-reconciliation repentance cycle each time he teaches us something new. Because we retain the spirit, we are able to learn more, faster.
We can obtain more awareness by making our “eye single to the glory of God,” or desiring to understand and obey all the truth of which we are aware. Anything less than this is rebellion against God: “Son of man, thou dwellest in the midst of a rebellious house, which have eyes to see, and see not; they have ears to hear, and hear not: for they are a rebellious house.” (Ezekiel 12:2)
Those who do otherwise either rebel against what their eyes show them, or they believe all they see is all there is to see, and thereby cut themselves off from anything better than what they have (see Matthew 13:15-17, quoted above).
Acquisition of knowledge requires obedience to everything you know as you know it.
34 He that receiveth of God, let him account it of God; and let him rejoice that he is accounted of God worthy to receive.
35 And by giving heed and doing these things which ye have received, and which ye shall hereafter receive—and the kingdom is given you of the Father, and power to overcome all things which are not ordained of him— (D&C 50)
