I'm not going to lie and say "It's okay" like everyone else. Because it isn't okay.
Matthew 6:19-21 “Do not store up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but store up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.
1 Timothy 6:9 But those who desire to be rich fall into temptation, into a snare, into many senseless and harmful desires that plunge people into ruin and destruction.
1 Corinthians 5:11 But now I am writing to you not to associate with anyone who calls themself a Christian if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a person.
Luke 14:33 So likewise, whoever of you does not forsake all that he has cannot be My disciple.
Anyone who calls them self a Christian shouldn't be concerned about material things. Not even food, cloths, or water:
Matthew 6:31 “Therefore do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For after all these things the Gentiles seek. For your heavenly Father knows that you need all these things. 33 But first seek the kingdom of God and His righteousness, and all these things shall be added to you. 34 Therefore do not worry about tomorrow, for tomorrow will worry about itself. Sufficient for the day is its own trouble.
To sum it all up: Yes, it's bad. God said to love Him above everything else. The Bible also says that anyone who loves their possessions CANNOT love God too (Matthew 6:24). I can tell you aren't a really devoted Christian. You probably just go to Church with your parents. I would suggest buying and reading the Bible for yourself (I prefer NKJV. It takes some getting used to, but is very good. Absolutely avoid the MSG, voice, and NIV. Those can hardly even be called Bibles anymore.)
