Only One Rock gets you into heaven
I am a true metalhead. But i'm also a Christian and i believe in God. If you are wondering what kind of metal, i like:
Arch Enemy Megadeth Metallica Protest the Hero Between the Buried and Me and others. (I can't post URLS, so you are free to check them a Wikipedia or Youtube.)
As you can guess, there are of growling and "unpleasant noises" from most people. I love them, as i have always loved the genre and will always appreciate it. It's so energetic, it makes me stand up and jump. I love it, and i won't deny it.
Am i Satanic? I go to church every Sunday, and i have helped in my local community as a translator (I'm Mexican, but i speak English) and helping with other stuff. =)
God's Holy Spirit transforms a human soul when Christ enters the life and everything changes. That is not a local church doctrine but a declaration of the Bible itself. (see 2 Corinthians, chapter 5) Everything inside of us changes when we truly meet Christ.
And yet we are still people. I still drink water, eat hamburgers, wear jeans, drive a little too fast, and I like music from most every age, and from many, many cultures. My favorite music of all time is Handel's Messiah.
In my case, because of the drug culture I was into when Christ rescued me, I made a conscious choice to set aside all the music that reminds me of that whole frame of mind. Now, I can't stand to listen to it.
Other men and women of God, however, have not only continued to enjoy various forms of rock music, they have used such in their ministry. Larry Norman, is one that comes to mind. He and a great many others of that general time period (roughly my own time period in the drug culture: 60s and 70s, etc.) did some good, speaking to generations of people through a medium that the world accepts. Some of the messages were as the voice of a prophet, calling kids and adults alike to repentance and faith in Jesus Christ. I thank God for every such witness.
As for whether or not you are satanic or maybe a real Christian, music is not the telling factor. Only Jesus Himself makes the difference.
If you know Jesus Christ (not merely as an idea, a historical hero or religious icon, but as your own Savior and Friend and Teacher in all of life), then you belong to God and you are a genuine Christian. On the other hand, if music and church activities and some good works are all that's going on in your life, then you should continue to listen to that concern and nagging discomfort that is using music to get your attention.
God loves you. Jesus died to save you. He knows your life, your needs, your potential future. He also knows the way into your heart. Call on Jesus, and admit that you need Him as a Savior and as the Lord of your life. If things remain confusing, then ask the Lord to help you understand what He wants from you. Find a local group of Christians who love Jesus and who will take the time to share the Scriptures with you. Allow God to make whatever changes He wants in your life. Music might be a part of that change or it may not.
The Bible (specifically the Psalms) calls God a mighty Rock of safety in times of terrible danger. Jesus is that Rock. He alone can get you into the kingdom of God as a real child of God. Pray to Him, learn about Him, follow Him, stay with Him. He is the only Rock worth living for and dying for.
