1Co 1:5 KJV That in every thing ye are enriched by him, in all utterance, and in all knowledge;
Paul here is talking about the Grace of our Lord Jesus Christ, that it was given that we may be enriched in utterance and knowledge.
There are two kinds of knowledge in the bible.
This is the kind of knowledge a Christian should have on God.
This is a general understanding of doctrine, and way of doing a matter, in order to live right and do right in regards to that matter.
In the above verse, the knowledge here is gnosis.
So 1 Corinthian 1:5 says we are enriched in all gnosis, meaning God gives us the understanding of all matters.
This causes us to walk with understanding in regards to all matters of doctrine. We no longer become religious robots, but we walk in understanding.
This is what grace does.
