The Fruit of the Spirit Part 8: Self-Control

ἐγκράτεια (G 1466) Self control.
This is the ability to not be governed by one’s own passions.
Vine’s Dictionary states the following “the various powers bestowed by God upon man are capable of abuse; the right use demands the controlling power of the will under the operation of the Spirit of God; in Acts 24:25 the word follows “righteousness,” which represents God’s claims, self-control being man’s response thereto; in 2 Pet. 1:6, it follows “knowledge,” suggesting that what is learned requires to be put into practice.”[1]
"For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ." (2 Peter 1:8, NASB95)
Self control is mentioned in 2 Peter 1:6 and is one of the qualities referenced in the verse above. A person who has little or no self control is useless to God. A lack of self control will impact every area of one’s life in a negative way.
