Ideas are things. Real things. They come into existence as we create them. They will become subject to the judgment of God, because our thoughts are perhaps the most real part of us. (See Alma 12: 14.)
We should guard our thoughts as we guard the lives of our children. Our thoughts hold the key to everything else.
This is so important a matter that the Lord tied knowledge of priesthood itself to the thoughts we entertain in the privacy of our minds. Only when our thoughts are worthy are we able to bear the presence of God. (D&C 121: 45.)
If you study the scriptures and then meditate upon them also. You will only develop power within as you do so.
Yet another reason I love our hymns… ;-)
James Allen’s “As A Man Thinketh” comes to mind.
