"Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things." (Phil. 4:8)
Larry Elder is a famous 'talk radio' libertarian who uses a really 'catchy' catch-phrase: "Truth beats all." And how true that is. Truth is foundational to Christian living, and in this case Christian thinking. Paul was perhaps trying to calm the mind of his readers since they are longing to know about his condition. The truth of the matter was that Paul did not allow his circumstances to ruin his calling and ministry. As Christians we have a responsibility to make decisions based on the truth. Where is truth? where do we find truth today? Jesus said in John 17:17 "Sanctify them through thy truth: thy Word is truth." We have all of God's truths in the Bible. The Bible speaks truths about the Second Coming of our Lord and Saviour Jesus Christ, it speaks to us about a future judgment day (Judgment Seat for those saved; and the Great White Throne Judgment for those who are unsaved). It speaks truth that often we may not like to hear, but it speaks about it anyway...loud and clear. Part of the reason I have great difficulty and even discomfort (better yet a distate) for Hollywood Movies is the fact that much of what they 'put out' is truly morally, and doctrinally untrue. Our young people are promised happiness in booze, cigarrettes, and promiscuity however, the truth is that happiness is found in serving the Lord instead of self. In fact, one cannot serve two masters (see Matt. 6:24). The truth says "wide is the gate and broad is the way that leadeth to destruction" (Matt. 7:13b).
There are many other things I would love to say about 'truth' so many verses one could consider. I think this will do for now.
