Are you the only surviving Christian in your family? Maybe you're the only one that goes to church, or the only Christian at your place of work or in your neighborhood. There may even be a number of people around you who call themselves Christians, but are lukewarm (Rv 3:16), not totally committed to the Lord, straddling the issue (1 Kgs 18:21).
You need to be another Elijah and call people to repentance and total commitment to the Lord. Ask Him where your Mt. Carmel, your battlefield, is (see 1 Kgs 18:20ff). Ask Him whom you are to confront, and when and how to do it. Your battlefield may be the bedroom, backyard, or church. You may be called to confront your oldest son, a boss, an employee, or twenty co- workers. You may need to do this immediately, the next time you see them, or after praying a novena. You may be called to focus your battle on calling others to go to Confession, forgive a spouse, repent of having an abortion, face their addictions, or swallow their pride.
The battle belongs to the Lord (1 Sm 17:47). He is telling us the details of the battle so we can share in the victory. Listen and fight.
