Expositor's Bible Commentary Commentary John 7:18

"He that speaketh from himself seeketh his own glory: but he that seeketh the glory of him that sent him, the same is true, and no unrighteousness is in him." — John 7:18 (ASV)

“If any one chooses to do God’s will” means there must be a definite act of the human will in order to do God’s will—a settled, determined purpose to fulfill it. Spiritual understanding is not produced solely by learning facts or procedures; rather, it depends on obedience to known truth. Obedience to God’s known will develops discernment between falsehood and truth.
