1.Cor1,4 I always thank God for you because of his grace given you in Christ Jesus. > Paul thanks God for the church in Corinth! Because through the church in Corinth Paul gets God's grace. The church in Corinth is Grace given by God to Paul. That is how Paul feels!
About to me strangest person in the kingdom : Do i feel like this towards him, her?
Do i see, that every one in the church is a gracious gift from God towards me!
People :  We are way to critical about each other!5 For in him you have been enriched in every way- in all your speaking and in all your knowledge-
> God changed people already! They are so different since they became disciples. They speak differently, they know God - love, grace, mercy ... God did that.
God worked on to me most wired people!
6 because our testimony about Christ was confirmed in you./6 wie denn das Zeugnis des Christus unter4 euch gefestigt worden ist.  > Christ becomes stronger in them - of corse then ever. Because it was not in them before!
7 Therefore you do not lack any spiritual gift as you eagerly wait for our Lord Jesus Christ to be revealed. > They have no shortcomings ... They have the holy spirit too. God is giving them thoughts in their heart for me too!
What does eagerly waiting for the Lord Jesus Christ change in me? Am I eagerly waiting for the Lord Jesus Christ? 
8 He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ. > Here it comes again. HE WILL KEEP YOU STRONG TO THE END!
I do not understand that at all! HE - through people? How - why he! What is going on! What are we doing? What are we hoping for? What are we supposed to do?
Röm 13,8 Seid niemand irgendetwas schuldig, als nur einander zu lieben! Denn wer den anderen liebt, hat das Gesetz erfüllt. /8 Let no debt remain outstanding, except the continuing debt to love one another, for he who loves his fellow-man has fulfilled the law. 
> To all of us who know it, all, every thing better: Give the love!
9 God, who has called you into fellowship with his Son Jesus Christ our Lord, is faithful.
> Funny that he is saying this now. 

Am i faithful to my fellow disciples?
Am i giving love?
Am i deeply thankful for even the strangest disciple in the kingdom of God? Do i see how i belong to him/her?
What ever i do, where ever i am, GOD IS FAITHFUL!
