Understanding what is true and truthful is the most important task of Christians, and people in general. Why? We have to know the truth of Jesus Christ and his saving grace in context of the truth of the God of the Bible, our relationship to God, and how to live a Christianly life in this world full of lies.
If we don’t seek to understand what is TRUE in this world, our decisions and actions may lead us down wrong paths and dead ends of the devil’s deceptions that we willingly chose to tread, simply because we didn’t bother to question what is true. We need to know what is spiritually TRUE, and also what is TRUE in the world around us.
