Adam Clarke on 2 Corinthians 5:9

Wherefore we labor - Φιλοτιμουμεθα· from φιλος, loving, and τιμη, honor; we act at all times on the principles of honor; we are, in the proper sense of the word, ambitious to do and say every thing consistently with our high vocation: and, as we claim kindred to the inhabitants of heaven, to act as they do.

We may be accepted of him - Ευαρεστοι αυτῳ ειναι To be pleasing to him. Through the love we have to God, we study and labor to please him. This is and will be our heaven, to study to love, please, and serve him from whom we have received both our being and its blessings.
