When God in His sovereign benignity communicates grace to a person it is for the purpose of equipping him for the better discharge of his responsibilities. That is to say, grace is given to animate and actuate all the faculties of his soul. And what He works in, we are to work out (Phil. 2:12-13). Having imparted life to His people,, He requires them to walk in newness of life. Having bestowed faith on them, He expects that faith to be active in producing good works. Or, following the order of this prayer, if we have been ‘filled with the knowledge of his will in all wisdom and spiritual understanding’ it is in order that we ‘might walk worthy of the Lord unto all pleasing, being fruitful in every good work.’ Those last words express both variety and abundance. It is not fruitfulness of one kind only, but of every sort. Said the Lord Jesus, ‘Herein is my Father glorified, that ye bear much fruit’ (John 15:8). Alas, that any of His children should be content if they can just be persuaded that they bear a little fruit and thereby be convinced they belong to His family – setting more store on their own peace than upon their glorifying Him. Little wonder their assurance is so feeble.
