Righteousness In Us For Justice

For everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. - Heb 5:13-14

Solid food refers to the word of righteousness. The more we train our mind (powers of discernment, which refers to the senses; in Greek, it is aisthétérion, which means the faculty of the mind and perception) on righteousness, the more we are able to distinguish good from evil.

At that time God enthroned the mind above all as the holy leader, through the medium of the senses. He gave a law to this mind, by living according to which it will maintain a temperate, just, good, and courageous reign. - 4 Macc 2:22-23

The Right-ness in us loves Justice and hates injustice.
