If you removed about 90% of it and just left the "love thy neighbor" type of stuff it would be relevant. No one can expect a 1,600 year old book to remain relevant forever, what foods should or should not be eaten, how to care for your slaves, etc. just aren't important in today's world.
This is in reply to the question, "Is the Bible relevant in the 21st century?" The Bible is absolutely necessary, esp. in these times. We are living in what is known as "The End Times," and every person should be very concerned as to what to do at this time. I'm not sure how much I can write here, but let me say that the Bible is God's Word; it is life; it is truth; it is to be taken seriously and right now. I prefer the New King James Version, esp. because Jesus' words are written in red ink. Please buy a Bible and start reading. God will guide you through it. Get in a good Bible-teaching/preaching church. The Bible is meant for everyone right down until the return of Christ, and because it is truth, my guess is that it will be used in the millenium (when Christ rules for 1,000 years). There is so much to say, and I am glad you asked that question. Yes, is the answer. God bless you.
It never was or will be in the perceivable future. Religion was formulated for the purpose of crowd, and population control. Now they are finding out that this form of thinking did not work. But it sure has made people a lot of money. Not to mention a free ride from the government.
Yes, it is. It's over a thousand years old, so some of the stuff doesn't even exist anymore. But the morals and truths still work the same way they did then. That's what the Bible teaches. The truths don't change as years progress although many people would say otherwise. The Bible is relevant, just as it was 2,000 or so years ago. If you read it, you'll see how the world has decided not to listen to it, but that doesn't mean the truths have changed. The people have changed and corrupted this world.
Is the Bible relevant today In the 21st century, is the Word of God still as powerful as it was in Hebrews 4:12, when it was described as "living and active and sharper than any two-edged sword?" Is our Bible today the same divinely-inspired book that Paul spoke of to Timothy in 2 Timothy 3:16-17, praising it as "profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work" The answer is,"Yes!"
The Bible that we hold in our hands today, translated from the original languages and passed down to us over the centuries, is just as profitable for every aspect of our lives in the 21st century as it was for believers in the first century.
