Lao Tzu believes the desire to seek the wisdom of the Creator begins with self-discovery: understanding true human nature.
This is your living by faith. Living in this contemporary world is challenging and difficult. Why? Because there's too much information, disinformation, and misinformation, and thus you're easily led astray. Worse, you're living in your flesh--which means your thinking mind is controlled by your physical desires.
According to Albert Einstein, thinking is everything in everyday life and living, but people seldom do it. In other words, your human wisdom is inadequate and incomplete. So, you need your spiritual wisdom to help you in your everyday life choices and decision. But believing in God is a tall order. The journey of faith is long and winding with many obstacles, detours, and sidetracks.
But once you've your faith, your living by faith will help you in your actions and inactions, as well as in your choices and decision, in your everyday life and living.
