Matthew 5:16 – Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
There’s no need trying to explain God to be people who either deny or question His existence.
Simply worship, honor and obey His Commands and everyone else will know who He is. Trust me. god has a way of showing up in your life that’ll make others pay attention and glorify who they question or deny.
