Pray that the saints would be perfected in their personal fellowship with the Lord, learning to speak to the Lord genuinely from the heart and to pray according to the anointing Spirit moving in their spirit (John 4:23-24 and note 245; 1 John 2:20, 27; Hymns, #784, s. 4 and chorus).
John 4:23-24—But an hour is coming, and it is now, when the true worshippers will worship the Father in spirit and truthfulness, for the Father also seeks such to worship Him. God is Spirit, and those who worship Him must worship in spirit and truthfulness.
1 John 2:20, 27—And you have an anointing from the Holy One, and all of you know…And as for you, the anointing which you have received from Him abides in you, and you have no need that anyone teach you; but as His anointing teaches you concerning all things and is true and is not a lie, and even as it has taught you, abide in Him.
