These three questions seem to plague Christian controversy the most! I will try to approach each topic with as much consideration, and Biblical direction as I can! Hope you enjoy!
What can I watch? What can I read?
So, these first two questions go right along with one another. Many people struggle with what to read or watch because it most likely is coming in from the secular world. I've been struggling with this concept quite a bit with the release of the new Harry Potter edition. Of course, I went ahead and read it before I dove in trying to figure out if this is okay. I know that in many places the Bible says that we should have nothing to do with witchcraft. However, this applies to existing witchcraft, I really hope that you wouldn't believe that Harry Potter is a non-fiction tale. And, if it makes you feel much better, J.K. Rowling and many other places have delved into the concept of Christian allegory placed in the seventh Harry Potter novel. Then comes the question, what about fiction? Technically, fiction is not truthful, therefore some people call it lying. There are a few places in the Bible that I would like to point you to in these questions. The first is 1 Corinthians 10:23-24, "'I have the right to do anything,' you say, but not everything is beneficial 'I have the right to do anything,' you say, but not everything is constructive. No one should seek their own good, but the good of others." This goes in more depth later on in 1 Corinthians chapter 10 as well. But, with these two verses, we see that as long as what you're watching or reading is not interfering with the good of others, and that you always have the good of others in mind, you are okay to continue forward. This does not mean that you should watch and read everything! Just because it says it's okay, per se, don't go about reading things that will change your well-being, because if you change, that affects the people around you drastically. If you get in to reading secular novels or watching secular television, be aware of what's going on inside of you and around you. If you're attitude picks up, you are not working for the well-being of others, target that problem and get rid of it. If some sort of depression sets in because of what you've devoted your time to, put the book down and pick up the good and joyful Bible. Nothing you do on earth should cause you to shy away from your walk with God. If reading Harry Potter or Lord of the Rings or anything along those lines, puts you in a situation where you question your faith, then STOP READING THEM! As long as you are sure that there is nothing on the earth you hold above God and Jesus Christ. I know that you might be tempted to say that nothing on earth you could possibly hold above God. That is false, I'm so sorry to tell you. When you sin on earth, you are pushing God out of your mind because you're afraid. Of course, we know that through Jesus you are forgiven of your sins, but they are still sins. Even though you know you have the Savior, Satan is still coming after you. If you fall to sin, then you're on the road to falling from God, Satan is always ready to lead you away. Don't let what earthly things you do be the cause of this new and treacherous path that brings you away from God.
What can I eat?
I know that there is a big long list of things in Leviticus that we cannot eat. Unfortunately, this has become the target point from secular, and even some Christians, rationalizations of other sins that have come in to this world. There are two quick places in the New Testament that I'm going to take you to bring an answer to these accusations used to rationalize other sins. The first is Mark 7:17-19, "After he had left the crowd and entered the house, his disciples asked him about his parable" (see earlier in Mark 7 for the parable) "'Are you so dull?' [Jesus] asked. 'Don't you see that nothing that enters a person from the outside can defile them? For it doesn't go into their heart but into their stomach, and then out the body.' (in saying this, Jesus declared all foods clean.)" The second place in the Bible is Acts 10:10-15, "[Peter] became hungry and wanted something to eat, and while the meal was being prepared, he fell into a trance. He saw heaven opened up and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles and birds. Then a voice told him, 'Get up, Peter. Kill and eat.'
"'Surely not, Lord!' Peter replied. 'I have never eaten anything impure or unclean.'
"The voice spoke to him a second time, 'Do not call anything impure that God has made clean.'"
I feel like these two sets of verses don't need anymore explanation than what is presented in and of themselves, but in case you do have questions, tweet me! My twitter will be above with the quote from John Wesley.
I hope that this long post provided a little insight into helping you decide how to live your life on the Christian walk with Jesus. I will add one more thing to the first question, I have come to the conclusion of stopping watching cable television. Note! This is my own personal preference, not a condemnation for other people! I came to this conclusion because of the increased secularism, dramatization, rationalization of sin, and flat out sadness and discomfort each show leaves me with. I went back to my childhood years of watching Disney movies, and reading, lots of reading. Old Disney movies and just old shows from the 20th century, are much better and more appropriate for all ages in my opinion. I will write again soon! Have a great night! And God bless!
