AnilM, I am praying for you
Dear AnilM, Many of us Christians are dealing with spiritual warfare. We need to fight back like Christian soldiers on the battlefield. Reject every ungodly and intrusive thought and replace them with quotes from Scriptures; this is indeed our weapon. When Lord Jesus was tempted in the wilderness by Satan, he fought back by quoting from the Word of God. (See Matthew 4:1-11). I also encourage you to read Ephesians 6:10-18 about the armor of God. AnilM, you also might find it helpful to read two articles on the gotquestions.org website, namely, "What does the Bible say about spiritual warfare?" and "How can I take control of my thoughts?" I hope this information will strengthen you. May all go well in your Christian walk. In Jesus's name, I pray.
Jesus answered, "The work of God is this To believe in the one he has sent." —John 6:29
