Now, what does Phil. 4:8 really mean? I once heard a teaching, which I think was given by Chuck Swindoll, which discribed the elements of Philippians this way:
When the Apostle Paul addresses "true" things, he is referring to those things laid out for us in accordance with Scripture, the infalliable Word of God. They are the things that are the opposite of dishonest and unreliable things.
"Noble" refers to that which is dignified and worthy of respect.
"Right" refers to conformity to God's standards.
"Pure" refers to that which is wholesome, not mixed with moral impurity.
"Lovely" speaks of what promotes peace rather then conflict.
"Admirable" relates to what is positive and constructive rather then negative and destructive.
These 6 "objects of thought" are then described as excellent and praiseworthy.
