“But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.”
King James Version (KJV)
5:14 But strong meat - These sublimer truths relating to perfection, #Heb 6:1|. Belong to them of full age, who by habit - Habit here signifies strength of spiritual understanding, arising from maturity of spiritual age. By, or in consequence of, this habit they exercise themselves in these things with ease, readiness, cheerfulness, and profit.
Heb 5:14 Strong meat belongeth to them that are of full age. When one has reached manhood we do not expect him to live on the food of babes. So a church member, as time goes on, ought to feed on "solid food" (Revised Version), the higher teaching of religion. There should be growth in knowledge. Have their senses exercised to discern both good and evil. The reference here is to the faculties of the soul. A Christian ought to study, to gain a thorough knowledge of the Scriptures and especially of the New Testament to become able to teach others, and to explain the higher principles of our religion. In addition he ought to be able to discern the moral character of the environments of life, to know not only what to accept and what to reject, but how to warn his less instructed brethren.
