“And account that the long-suffering of our Lord is salvation; even as our beloved brother _Paul_ also according to the wisdom given unto him hath written unto you; as also in all _his epistles_, speaking in them of these things; _in which are some things hard to be understood_, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.” 2 Peter 3:15, 16. NOTE.—Some scriptures are too plain to be misunderstood, while the meaning of others cannot so readily be discerned. To obtain a comprehensive knowledge of any Bible truth, scripture must be compared with scripture, and there should be “careful research and prayerful reflection.” But all such study will be richly rewarded. 6.

Why cannot the natural man receive the things of the Spirit? “But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, _because they are spiritually discerned_.” 1 Cor. 2:14. 10.
