‘Proving what is well pleasing to the Lord.'
‘Proving.' (dokimazo). ‘Putting to the test, examining.' Everything we do and are must be brought to His light to be examined and tested. This does not mean negatively, by examining our lives through a microscope for every possible defect, resulting in continual self-doubt, but a positive willingness to let the light reveal our failures and what our way ahead should be. We should live our lives before the Lord desiring only to please Him. We too should be a sweet smelling perfume to Him (compare Ephesians 5:2).
