Saint Francis of Assisi wrote the following Prayer which I (Mother Teresa) like very much.The Misionaries of charity pray it every day:

Lord make me an instrument of your peace:
where there is hatred let me sow love ;
where there is injury, pardon ;
where there is doubt, faith ;
where there is despair, hope ;
where there is darkness, light ;
where there is sadnes, joy.
Lord, may I not so much seek
to be consoled as to console ;
to be understood as to understand ;
to be loved as to love.
Because it is in giving that we recieve,
in pardoning that we are pardoned.

(From the book "Mother Teresa in My Words" ).

"And you shall know the truth, and the truth shall make you free." said Jesus.( John. 8:32)

Jesus..!! When You talked about Freedom,and Muhammad(peace be upon him) talked about Freedom..Then why do they imprison us by taking your names.??

The Question usually Arises that what should be the Foundation of Religion,,
Is it Entirely Faith ( Fideism) or Is it Entirely Reason (natural theology)...
This is one of the Initial Questions which we encounter when we enter in the field of Philosophy of Religion,,

There have been different School of Thought with in Religious people in answering this Question,,
Efforts have been done in Weakening of Reason as in “Critic of Pure Reason” by Immuel Kant and Heavy Arguments were given Relying only on Faith like Pascal Wagner and Imam Ghazali.,,
Rise of Reason was preached by St Thomas Aquinas as in his “Summa Theologiae” and list of Muslim and other religious dialectal theologists,
Few Mixed arguments given by Allama Iqbal in “Reconstruction of thoughts in Islam”

I try to put my point of View on it,,

REASON:
---------------
Reason can never be established until we accept the authenticity of Knowledge along with its Sources. By Criticizing Knowledge and its sources It will end in Either Nihilism or Fideism,,
If Sources of Truth are corrupted or have disability to Establish the Truth then Truth can never be achieved,, this will end in nihilism,,, which will end in the Death of Religion,, Nietzsche said " Religion is Dead,, God is Dead" by having this nihilistic Approach. This is also Anti Religious Behavior which we frequently find in religious people,,,,
Sources of Knowledge even with all of their limitations are reliable to establish the Truth. All the discipline of knowledge can be trusted on these Sources,,
I have never been in Opposition of the Existence of Faith Entirely like ‘Natural Theologists’,, they claim that "everything is understandable or conceivable by Reason alone, No Faith is required”. I favor the Necessity of Faith like Pascal writes in ‘Pensees’,“If we submit everything to reason,our religion will have no mysterious or supernatural element”.Relying purely on Reason destroys the Concept of Revelations,, Revelation clearly proposes certain truths which might never have been discovered by reason unaided, although they are not of themselves inaccessible to reason.

I maintain that Reason will be the Check on Revelations,, Scrutinization of Revelations by Reason goes in favor of Religion,,, and As the Light of Truth from Reason will show us what to have Faith in..

FAITH:
-----------
In theology Faith is usually defined "believing without Reason",,Many Religions in the World Claim to Stand only on Faith,,, Either they fail to give the reason OR avoid OR are not interested in Reasoning,, they Maintain the Position that their Faith,,intuition Spirituality is sufficient enough to Prove their Claim ( Religion),
Pascal Beautifully Said "The Heart knows the Reasons which reasons not know of" sounds very beautiful but to build the Tower of Religion entire only on Faith,,I have objection on it,,
ISLAM can not stand on Fideism ( only on Faith),, The Entire building of the Religion based on Fideism can be perished in one question
"If faith is the only way to know the truth of God, how are we to know which God to have faith in"
Deprived of reason, faith has stressed feeling and experience, and so run the risk of no longer being a universal proposition. It is an illusion to think that faith, tied to weak reasoning, might be more penetrating; on the contrary, faith then runs the grave risk of withering into myth or superstition. It is Reason which Differentiates between Faith and myth or Superstition..

CONCLUSION:
----------------------
Two Great Religions ISLAM and Christianity,, which encircle more than 50% of the population of the world,,Majority of Scholars in them ( except few) always forced the importance of Reason with Faith,, Reason has always been their way to Reach the Faith,
It is Either by ignorant People who claim to be religious but are not aware of Knowledge or by Arrogant Anti Religious People who are in constant struggle of giving the impression that foundation of religion is very weak as it is Only Faith and no reason at all,

" Faith and reason are like two wings on which the human spirit rises to the contemplation of truth;" (Bible)

John Pope Paul II says in his letter to all churches,,
"This is why I make this strong and insistent appeal — not, I trust, untimely — that faith and philosophy recover the profound unity which allows them to stand in harmony with their nature without compromising their mutual autonomy. The parrhesia of faith must be matched by the boldness of reason."

Note: I don’t doubt the Sincerity of Ghazali,Pascal all those religious people who gave more importance to Faith and took Reason as very narrow and limited,,It was all in their good intention in defense of Religion,,

In Last I have Faith that When the Light of Truth by Reason will Shine,,, The beauty of ISLAM will catch the sight of every one,,Perfection of ISLAM will be revealed,,

I believe that Knowledge should be Free,,, Every Discipline, Source and Branch of Knowledge
( Philosophy , Science, Reason, etc) should be Free from every Dogma, Every Ideology,, Every Religion, Every Anti-Religious Approach( the attitude where Religious ideologies are tried to be proven wrong on the sacrifice of Knowledge),,
Knowledge should be Pure and it should be Immune from any External Interference.
History the most Celebrated Academic Discipline doesn’t Have any Religion,, Same with Science and Philosophy,,, The Down Fall and Crisis of Knowledge is because of these sources( which are used to Find Truth) are Corrupted by External Stimuli of partiality,,,which includes both religious and anti-religious thinking...

I m sure When Knowledge will be Free then Religion will be Victorious against anti-religious forces,,, And Being a Muslim I have Faith that ISLAM will Emerge as the Only and Nearest Religion from Nature of Human Being,,,

Today I watched the Movie called "Woh Lamhe",One Scene from the Movie is still revolving in my Mind,,, Where The Lady is lying on the Bed in ICU,, counting her last breaths,, He says " I will kill you,, Really I will,If you leave me,You are not going,You wont Die" with tears and hope in his eyes", ,,,, He is watching his life Dying in his Arms.She is Quiet and looking at him,,Man Cries and Holds her tight as one holds someone not let one Go,,put his head on her chest and keep repeating the same " you are not going anywhere",, Lady stops breathing,,,He is still holding the Body but the Soul left him,,,
The Fate of Lady to die in the arms of Man she wanted most.The Man Most Unfortunate who lost the reason to live,,,
