Faith is the organ of knowledge, and love an organ of experience. God came to us in the incarnation; in the atonement He reconciled us to himself, and by faith and love we enter and lay hold on Him.
A.W. Tozer, The Knowledge of the Holy
Love is not a static word, it is a verb and so by definition expresses action. The action love expresses is displayed through selflessness, & service. Jesus said that our love for God would be seen in our love for the least of these. (I have already written much on this point.)
Faith, likewise, is also a action word. However Faith is either continual tense, or past tense. You either had faith, or you continue to still have faith. We best understand faith by the words we use to substitute it with like trust, and belief. I trust in God, I believe in God, I have faith in God. Yet, we use the word belief or believe to talk about faith a problem arises. Because when when many of us talk about belief or believing in something we can do it without effecting our present reality. Belief has become nothing more than a statement or agreement. A common point to gather, but leave separate when its over. Trust on the other hand is a good substitute. Because when we trust we are moved to a place of reliance, beyond mere belief. Yes we believe in God, but we also trust in God. As Tozer wrote, Faith is that organ of knowledge, but it does not stop there, it moves past belief to trust and in trust we are required to act. If your faith is alive and well it will be displayed through your life and deeds. You faith is in a state of continual use, or it is in past tense…dead.
