By His Glory, We Do All in His Glory, and Thus We Glorify Him

"31Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God." (1 Corinthians 10: 31)

We do everything by the grace of God, which we receive through Christ Jesus:

"30But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 31That, according as it is written, He that glorieth, let him glory in the Lord." (1 Corinthians 1: 30-31)

In fact, the whole Gospel is about receiving Jesus' own glory by grace through faith:

"Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ." (2 Thessalonians 2: 14)

and then

"But God, who is rich in mercy, for his great love wherewith he loved us, 5Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) 6And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:" (Ephesians 2: 4-6)

Our glory comes from Jesus, for God Has adopted us (Romans 8: 15), and thus God the Father sees as Jesus His own Son:

"17Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world." (1 John 4: 17)

Our glory in Him, that through His glory we would glory in Him and glorify Him, was God's plan from the beginning:

"Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified." (Romans 8: 30)

This glory we receive because of the righteousness of God given to us in Christ:

"For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ." (Romans 5: 17)

and

"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)
