Faith

Our Faith in God always begins on a crutch.
A crutch— a strong supporting Faith, that has been passed down to us, through the Holy lives of Faithful Christians.

We hold on to it; we believe in it; we live and grow upon it.
Then eventually by God's Grace, we ourselves become the beacon— the "light of Christ",  that would continue to be passed down to future generations— as a living testimony of our Faith.

It is then, that we'll express the words (of our Faith) that resounds in the Holy Scripture :
"We no longer believe just because of what you said; now we have heard for ourselves, and we know that this man really is the Savior of the world." [John 4:42]

Every Christian who is determined to be a Faithful Christian, follows the same path, until he himself becomes the "light of Christ".
