“The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all. Amen.”
2 Corinthians 13:14

He prays for the church that the grace of the Lord Jesus Christ be with them; he wanted them to know about the grace of Jesus and be conscious of his grace at work in their lives, in your life; the Bible says:
“For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might be rich.” 2 Corinthians 8:9
He identified with you so you can identify with him freely; the Bible also says:
“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.” 2 Corinthians 5:21
When you believed the gospel, you became a recipient of and a participator in that grace, just by believing, not because of anything you did, you have been made the righteousness of God, you have been made rich- irrespective of what you see. Listen to Jesus:
“I know thy works… and poverty, (but thou art rich)…” Revelations 2:9
