The purpose of scripture and revelation is to set a standard of rules, and give examples of how and why to apply them. They also teach us about ourselves and God, and how that relationship works. Then there is advice about what is to come. They, therefore, set an approach to life that is wisest to follow.
Philosophy comes from the opposite direction in that it puts the person in the driver's seat. The person invents the laws that they should follow, according to their perception of life. They decide what God is and how the relationship works. It gives them the opportunity to philosophise away or bend anything God has said that doesn't suit. That way they get to create their own religion in a fuller sense.
One obvious failure of philosophy is that it has no standard to find a concept true or false. Each idea is a matter of opinion. The natural man takes over from the truths taught by God. And as man pursues these concepts problems begin to happen. Then man philosophises away these problems, and so they continue.
Serious wars generally eventuate and people slowly begin to turn back to God in fear of the outcome if they don't. We saw this in the Second World War. Then in the 50's there was this great progress and blessing that came as the world followed better principles. The blessings went on into the 60's. But in the latter 60's there began to be a moving away from God. It increased into the 70's and by the 80's we began to suffer the consequences. Recessions, drought, unemployment, aids, increased violence, drugs and economic downturns.
But philosiphers give us excuses for these things. And governments keep our minds busy on meaningless projects like not using plastic bags and worrying about the claimed "Green-house Effect". As if this will make the world better and solve the real problems.
People demand that the government do something about social problems. So governments create more laws to restrict social rights, as if this will resolve it, while the problem itself gets worse, because people don't turn to the real cause. They want the government to curb the natural result of sin by getting "tough" on those involved in its outcome.
It is time we turned from man's philosophy and ideas of resolutions to life's problems and turned back to the tried and proven methods of God.
To some extent we can all be guilty of philosophising religion. To help us God has given us scripture, prophets and personal revelation.
