In the same way that we need military, police, border guards, hospitals, homeland security, etc. to guard the natural areas of our lives, we also need spiritual watchmen to provide warning for our souls. Most people receive little to no training on how to see these kinds of dangers that can come our way.
Centuries ago, during a time that was particularly desperate and dangerous, God spoke to Ezekiel:
“Now as for you, son of man, I have appointed you a watchman for the house of Israel; so you will hear a message from My mouth and give them warning from Me.” – (Ezekiel 33:2-7 NASB)
