What is an agent? The Collins Concise Dictionary says that an agent is “a person who acts on behalf of another person, business, government etc.” ‘A person representing a business concern.” To represent means “to act as or be the authorized delegate or agent for (a person, country,etc.)” “to act as a substitute or proxy (for).”

Talk to my representative. Talk to my substitute.

What is Satan’s work? The answer is to accuse the brethren. Revelation 12:10: “For the accuser of our brethren is cast down, which accused them before our God day and night.”

My substitute is the Lord Jesus Christ.
