Now faith is confidence in what we hope for and assurance about what we do not see. (Hebrews 11:1 NIV)
There is much we must take on faith. We have only this moment and must have faith that there will be another after it. Such is the way of life and death.
But too so, we must have faith for a great many other things in life. It is when we accept assurance about what we cannot see or cannot know that faith becomes evident.
Additionally, how we live our lives will always reflect what we put our faith in.
