This is the doctrine of incremental insight, of revelation based on readiness, of precept upon precept; line upon line (Isa 28:10). The parable of the talents (and the very use of parables, themselves) teaches this same principle. At different times in our lives, we may only be ready for the Lord to give us one talent. Yet later he may find us worthy of two or five. If we are wise in our stewardship over the knowledge and revelation which he has given us, then more is given. When we waste the talent given to us by hardening our hearts, we will be left with nothing. As the Lord said, Take therefore the talent from him, and give it unto him which hath ten talents. For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath. (Matt 25:28-9)

"For my own part I can think of nothing that could be a greater offense against the majesty of God than for a man with his limited intellectual power presuming to pass judgment upon and rejecting the things of God, because forsooth, these things do not conform to his opinion of what the things of God should be like; or because the way in which they are revealed does not conform to the manner in which he thinks God should impart his truths. Such pride always has and always will separate men from receiving knowledge by divine communication. As Alma taught, 'he that will harden his heart, the same receiveth the lesser portion of the word' (Alma 12:10)." (Dallin H. Oaks, Pure in Heart, p. 93)
