The two go hand in hand. The more mature, deeper you are in your
walk the more truth God will reveal to you. But there are also other
things to consider, because obedience is key.
CERTAINLY! And we too have the Holy Spirit living in us now.
At that time Jesus promised them the Spirit, which would
lead them into all truth. This promise of the Spirit was to all
of those who are born again.
The passage I am familiar with is specifically addressed to the disciples. There might be others, but I don't know of any blanket promise to believers that they will be led in truth if they reject the authority of the Church. Jesus distinguishes between the disciples and those who will believe through their message.(US!)
Amen !! And i love you too CR.

May God bless you richly.
Amen and praise God.
Seek ye FIRST ... the KINGDOM of God.... and His RIGHEOUSNESS...
And THEN.... ALL... of 'these things' will be added unto you.
(Something I'm meditating on at the moment.)
I pray
that the God of our Lord Jesus Christ, the Father of glory,
may give unto you the spirit of wisdom and revelation in the knowledge
of him:
The eyes of your understanding being enlightened; that ye may know
what is the hope of his calling, and what the riches of the glory of his
inheritance in the saints,
And what is the exceeding greatness of his power to us-ward who believe,
according to the working of his mighty power, which he wrought in Christ,
when he raised him from the dead, and set him at his own right hand in
the heavenly places,
