Surely the Lord God does nothing, without revealing his secret to his servants the prophets. Amos 3:7
Do you believe this scripture applies to our age??
I do but I believe it applies to all the saints.
Joh 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
1Jn 2:27 But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.
Jas 1:5 If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
The preacher, or anyone else does not get more wisdom, or knowledge, of God's word than anyone else for all saints get all known to them equally.
The Spirit shows all the saints things to come equally.
God said He identifies Himself as the one true God by showing us the end from the beginning which no other religion or person will be able to do.
It is all in the Bible for all saints to know which God tells us what is going on today which is a useful tool because prophesy can reach out to people that the word of God is true for He told us what will happen, and we tell them what shall happen before it happens.
For years the saints have been saying the world will come together with a one world government, and religious system, and it will not be long and it will happen, and then what shall they say which many people will say they were right and then be curious about the word of God.
It does not always work saying God loves you, or Jesus loves you, to get their attention, but sometimes prophesy will get them.
