I Corinthians 1   Verses 1-9 are words of greeting and introduction. Paul, the "called" apostle - writes to the church at Corinth.   He addresses them as:
"those who have been sanctified in Christ Jesus"
"saints by calling" along with all who "call upon the name of our Lord Jesus Christ"

He blesses them with grace and peace from God the Father and the Lord Jesus.
He gives thanks for them because of the "grace of God which was given [them] in Christ Jesus." -
and then he adds this really stunning sentence -  "that in everything you were enriched in Him, in all speech and all knowledge ." enriched - made rich; wealthy- fullness;  

In Christ "all the fulness of Deity dwells in bodily form" (Colossians 2:10) tells us.. and "in Him, you have been made complete ( full).. " v11

Just read this yesterday and was struck by it.. and now here it is again.. when that happens I always feel like the Lord is talking to me!  Here Paul writes that we are enriched in speech and all knowledge.   How are we rich in speech?  What does that mean?  How can we be rich in "all knowledge "?   It says that this is by the "grace of God.. in Christ Jesus"... and that "you are not lacking in any gift". 

II Corinthians 8:7 says " But just as you abound in everything, in faith and utterance and knowledge and in all earnestness and in the love we inspired in you... "  and 9:11 ".. you will be enriched in everything for all liberality which through us is producing thanksgiving to God." Which points back to verse 8 " And God is able to make all grace abound to you ,that always having all sufficiency in everything, you may have an abundance for every good deed."  

So the abounding grace that God gives to us.. so that we have everything ... is meant to produce thanksgiving as we generously give to others:
through good deeds
through all we say,
through the knowledge of His Word ;
through our faith and
through love.

As Paul writes in II Cor. 9:10 " Now He who supplies seed to the sower and bread for food, will supply and multiply your seed for sowing and increase the harvest of your righteousness."  Which takes us right back to Hosea " Sow with a view to righteousness, reap in accordance with kindness.." (10:12)  And I am reminded again of the Truth that we reap what we sow..

God gives us everything... EVERYTHING by His grace!
He gives to us so that we may sow/ plant - for the purpose of righteousness.
And then He allows us to reap a wonderful harvest.. a crop that produces thanksgiving!

Father in heaven, You have given us "all knowledge".. what an amazing thought. Help us to receive it and live by it and sow it.. and reap a harvest of thanksgiving- to the praise of Your Holy Name.  What is lacking in my understanding, Lord God, please fill me.. that I might also have the testimony and the confirmation.. that I may be "blameless in the day of our Lord Jesus Christ".  Let Your will be done and Your kingdom come in all its fulness, I pray, in the name of the Savior, Jesus Christ the Lord. Amen.
