2 Corinthians 10:5 (KJV)
"Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ."
THREE THINGS young people can do to practice moral purity are:
First, choose their friends wisely (see Proverbs 13:20)
Second, guard what they put into their minds form books, movies, and music (see Psalms 101:3a, Proverbs 6:27)
Lastly, control their thought life (see Proverbs 23:7a, Philippians 4:8). The thought is the father of the deed. Someone has well said, “We cannot keep the birds from flying over our heads, but we can keep them from making a nest in our hair.”
“Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.” Philippians 4:8 King James Version (KJV)
