Peculiar! (The Sequel)

But what should this righteousness and obedience look like in YOUR life? That is something that would be difficult for me to say, unless I lived with you, going wherever you went, etc., which would be totally impractical. So here's what it looks like in my own life.
I'm 17 (19 now), I live at home, and I go to school at Peninsula College.

Friends:
Like I told my older sister, I treat other people who are carnally (worldly) minded in one of two ways: either tell them about Jesus or show them who Jesus is through my actions, but only if they decide to turn from sin and follow Jesus do I allow them a chance to be my friend. This results in my having very few friends, but for the sake of pureness of heart I refrain from allowing "evil communications" into my life [I Corinthians 15:33]. Basically, people that I know who are carnally minded are merely acquaintances, for I choose (and sometimes it is a hard choice) to be friends only to those who are Jesus' friends – those who obey Him [John 15:14]. Now, this does not mean that I do not talk or interact with worldly people, because I do (some of them may even consider me their "friend" – and I may be the best "friend" that they have), but it does mean that I do not allow them to influence my heart.

Home:
My standard for the music that I listen to is based on "evil communications corrupt good manners." [I Corinthians 15:33 and Proverbs 23:7] thus lyrics must be pure, edifying rather than degrading (e.g. "The Ballad of Davy Crockett" or "Snoopy Vs. the Red Baron" would be acceptable, whereas "Good Vibrations" or "Save a Horse, Ride a Cowboy" are not acceptable), and for Christian music (which most of it is, anyways) lyrics must provoke me to love and good works [Hebrews 10:24], and not lead me toward sin. I may like or dislike certain kinds of music, certain eras in music history, or certain artists, but music in and of itself is not inherently evil, but the intent of the musician (this can be difficult, if not impossible to determine, so most judgment depends on the lyrics) and the content of the lyrics are the qualities by which I judge music either good or bad.
Movies (this includes videogames), I judge by the same principle as music: I Corinthians 15:33. Knowing what scripture says about evil communications, I (and my parents and siblings) have a "three strikes and it's out/stepping into the pitch" rule: three bad words (see "Language" below) = stop and rewind or adultery/fornication portrayed in a positive light = stop and rewind. This doesn't leave many movies that are watchable, let alone well made or good… but I would rather risk the ridicule of my acquaintances than be cast into hell because the movies I watched had taught me to lust and/or to curse my Lord.
Books I hold to the same standard as movies.
Language: in scripture, we are commanded not to take the Lord's name in vain [Exodus 20:7] and again not to use filthy or corrupt language [Ephesians 4:29 and 5:3-4]. Having said that, here is a list of the words that I will not use, except in their proper manner, although sometimes not even then (for the sake of refraining from the "appearance of evil" [I Thessalonians 5:22]):

God's name – "Jesus/Christ/Jesus Christ/etc." without the respect/reverence due Him.
God's name in euphemistic form: "Gosh/Golly/Gee/Jeez/etc." all of which are God's name. In order to give people the benefit of the doubt, I do not usually credit people with knowing what they are actually doing when they say something like "Gosh darn it", unless I have already approached them about the subject.
"H---" usurping the power of God to send sinners there or belittling what God made it for. This includes the euphemistic forms such as "heck".
"D---" in a way that usurps God's authority. This also includes "less offensive" forms such as "darn" and "dang".
"S---/C---/etc." for this is filthy language to be sure. Euphemistic forms include "shoot", etc.
"F---" because as well as (in practically all uses) being vulgar and filthy, this degrades God's design for men/women in marriage. This includes euphemisms such as "frickin'".

Rather than showing myself to be filthy [Luke 6:45], I choose rather to maintain a pure heart and life…which includes the words that proceed out of my mouth.
Fortunately, because my parents are very good Christians, we do Bible study practically every night, reading about 4 chapters a night, as well as discussing any current questions or topics brought up in our home Bible study or that one of us may have had that needs addressing. Knowing the Word of God is extremely important! Keeping my sword from getting rusty and staying in practice with it are keys to using it well.

School:
Tedious and boring, I know, but in essence it is work (merely of the mind rather than the body, although those of you with writer's cramp may beg to differ); and thus I must, for conscience sake, do it as unto the Lord [Colossians 3:23], which means doing the best that I can do.
I don’t take part in many extracurricular activities, which is my own preference. BUT, if you do join the basketball team or whatever, be very careful in the "Friends" department: having to be around others who you would normally avoid can be a very good opportunity to witness, but it can also lead to their evil communications corrupting your good manners.
