Did I not speak peace unto your mind concerning the matter. What greater witness can you have than from God. –D&C 6:23
It is my testimony that if you do according to the Prophet Joseph’s invitation and “practice the principle of revelation” (1),you may learn to recognize when the words you are reading or writing are the “words of Christ,” or in other words, are being or have been delivered through the Spirit of the Lord. It is like recognizing the “voice print” of the Lord.
There comes a resonance into their writing (or yours)–whether the actual wording is simple or eloquent. There comes a “sound” that has the same effect on the human soul as the sounds of nature that bring us tranquility and peace. You can feel its effect almost like you can feel the effect of the sound of trickling water or calling birds–a soothing effect.
