Just read this
John 7:17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
Joh 8:31 Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed;
Joh 8:32 And ye shall know the truth, and the truth shall make you free.
Joh 8:38 I speak that which I have seen with my Father: and ye do that which ye have seen with your father.
Joh 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Well Gotta Love the Lord for such wisdom ey.
Usually when we get an understanding that is not from GOD, we are speaking of our own, and it is not from GOD. and it is unrighteous, and how do we know? NO Rest, peace. conviction settles in when we live that lie. troubled heart, sorrow that leads to repentance. Whatever GOD will throw at you in order that you repent
and leaving in TRUTH gives people liberty, has them Grow in faith. the bible says whoever commits sin is a servant of sin, so if we get an understanding from GOD, or a revelation from HIM and live in it. we get freedom from sin, and become servants of GOD. we gain freedom from a sin that was easily besetting us when we live in the TRUTH in the POWER and Guidance of the Holy Ghost.
what GOD recently taught me is that also, self righteousness is SPEAKING of oneself, seeking glory of oneself. that people may see that you are right, and not that the LORD is. seeking for the reward of men and not the reward of the FATHER.
and the bearing witness part can be tricky, ie. we can have 4 men that are living a lie, and even more than that (wide is the gate that leads to destruction). and quite a few that are living in truth (narrow is the gate that leads to life).
so i would always say to Exercise faith, and that we should see Major change in certain areas of our lives. Change that gives Glory to GOD.
