Ephesians 5:10

Proving what is acceptable - By walking in the light - under the influence of the Divine Spirit, according to the dictates of the Gospel, ye shall be able to try, and bring to full proof, that by which God is best pleased. Ye shall be able to please him well in all things.

Proving what is acceptable unto the Lord - That is," Walk as children of light Ephesians 5:8, thus showing what is acceptable to the Lord." Rosenmuller supposes that the participle is used here instead of the imperative. The meaning is, that by so living you will make a fair trial of what is acceptable to the Lord. The result on your happiness in this life and the next, will be such as to show that such a course is pleasing in his sight. Dr. Chandler, however, renders it as meaning that by this course they would show that they discerned and approved of what was acceptable to the Lord. See the notes on Romans 12:2, where a similar form of expression occurs.
