7:19,20 Every tree... is hewn down, and cast into the fire. The test of good and bad trees, good and bad men, good and bad systems, has been presented. Now the figure is carried further to show their destiny. The Savior states a principle that seems to run through the whole government of God. Whatever is useless and evil shall finally be swept away.
7:19 Every tree that bringeth not forth good fruit is hewn down and cast into the fire - How dreadful then is the condition of that teacher who hath brought no sinners to God!
7:15-20 Nothing so much prevents men from entering the strait gate, and becoming true followers of Christ, as the carnal, soothing, flattering doctrines of those who oppose the truth. They may be known by the drift and effects of their doctrines. Some part of their temper and conduct is contrary to the mind of Christ. Those opinions come not from God that lead to sin.
