What is the best way for others to know that we are Christian?

Is it by our words?

Is it by our actions?

Or, could it be by both our words and our actions?

The greatest proof of Christianity for others is not how far a man can logically analyze his reasons for believing, but how far in practice he will stake his life on his belief. -- T. S. Eliot

Genuine faith will always produce action, no matter what the cost.

Know that you are loved,
