Hebrews 1
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things,
John 10
1 Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber.
2 But he that entereth in by the door is the shepherd of the sheep.
3 To him the porter openeth; and
the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out. 4 And when he putteth forth his own sheep, he goeth before them, and
the sheep follow him: for they know his voice.
5 And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
IMO it should be the state of our relationship where we are talking to the Lord constantly and the Lord is talking to us. We have the Holy Ghost living on the inside of us. He is the one who teaches us, guides us, helps us and instructs us.
Also the Lord told me doesnt always mean there was a booming voice from heaven. It could mean God spoke, I could mean God illuminated a scripture that spoke to you, It could be a dream in which the Lord shared something, It could be a vision, It could be a prophetic word you received some one...
The Lord Told me IMO simply acknowledges GOD as the source of truth and revelation.
