Faith is not to have a perfect knowledge. When we have faith, we believe and act on things that we hope are true.
Faith is a very personal journey.
I have chosen to have faith in Jesus Christ and His gospel as taught in the Bible.
Does that mean that I know or I believe? Nope.
Does that make me better or worse than those who choose a different faith or don't profess any faith? Absolutely not.
What it does is inform my daily walk.
Engaging is participating even when you don't believe or know. It is caring for others and being part of a community.
