In our world, opinions come from all over. Just ask a question, and you'll get someone to let you know what they think, and possibly what you and everyone else should think. Sometimes you don't even have to ask! We may not always be able to solve the many difficult questions that arise in daily life, but we have no limit of people who are ready to voice their beliefs. If you don't think so, read "Dear Abby" or "Soundoff" for a few days! The topic doesn't necessarily have to be difficult or controversial.
Of course, there's nothing inherently wrong with people voicing their opinions, even about controversial and difficult matters. A problem arises when so few are able to give answers that are practical or helpful. Certainly, what is practical or helpful depends on the those doing the evaluating. But many - not all - are just "spouting off," perhaps parroting what someone else has said about the topic.
All of this applies to religious questions as well as other disciplines. For Christians, the Bible is the source of authority in answering our questions. What we need to do is get back in our Bibles. Let God speak. It's not as if he didn't have anything to say about the issues of life. After all, he is the creator of life, and he certainly knows how people ought to live it. There really aren't any questions or situations for which he has failed to provide direction.
This brings us to the importance of learning - and teaching - the Word of God. A vital passage, one familiar to many, is found in the record of Paul's second letter to his young disciple, Timothy: "Continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work" (2 Timothy 3:14-17).
Paul wanted Timothy to remember the value of Holy Scripture to his personal understanding and growth in God's will, as well as his work as a preacher of the gospel. Today, every Christian has a responsibility to learn God's will and to be involved somehow in teaching the Word to others. God doesn't speak directly today, except through his Word. And Christians are his means of speaking.
Regardless of the questions or tasks we face in life, let God get his Word in.
