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. John 16:13
Jesus told us exactly who would lead us into all truth.
Jesus is the Truth. The Holy Spirit bears witness of Jesus as the Truth.
Jesus saith unto him, I am the way, the truth, and the life:
no man cometh unto the Father, but by Me. John 14:5
We should always be learning with His Holy Spirit by our side.
Never ignore Him and never learn without checking with Him,
without verifying the truth with Him.
Jesus is a Living God.
When we choose to love the truth, He will honor that.
And with all deceivableness of unrighteousness in them that perish;
because they received not the love of the truth, that they might be saved.
2 Thessalonians 2:10
If we do not want to be misled or deceived, Jesus will keep us.
The more you seek the Lord, the more you read His word,
the less likely you will be to accept a false teaching
and the more likely you are to recognize mistruths.
And ye shall know the truth, and the truth shall make you free. John 8:32
Stay free from the doctrines of men, the lies, the error.
Know the truth.
Sanctify them through Thy truth: Thy word is truth. John 17:17
