When your public image doesn’t match who you are on the inside, it’s just a mask. Too many people want to protect their image by wearing various masks, but they leave their heart open to self-destructive and evil influences.
Hiding sin in your heart is like hiding a pebble in your shoe. Ouch! If you want to be mad about masks, get mad at the masks that you are wearing to hide what’s going on inside your heart.
In reality, masks are pointless. Regardless of how other people see you, you are whatever you really are on the inside. That’s what matters, not how well you hide behind your masks.
Church too often tries to get us to wear masks over our heart and just think about Jesus and/or merely believe that He lived. Instead church could train us to daily encounter and obey Jesus and be real with Him and with others. In Christianity, what you believe is important, but who you follow is more important. Do you openly follow and obey the living Jesus? Or do you just hide behind masks?
