In Reformed Theology what mechanisms and practices does God provide a believer to help fight temptation? Common answers are grace, prayer, Holy Spirit, and possibly others. **But how does God make grace work and what is our part in the fight?** Is there more than exerting our will mightily and when we fail we pick ourselves up, say sorry to God, and try again later at another fight? To help clarify the question, consider how a Reformed believer should respond when a Pentecostal friend confronts him/her of years of **showing no progress** over fighting a particular temptation (like anger, procrastination, laziness, etc.) The Pentecostal friend can say that **grace obviously doesn't work** and blame the Reformed believer for: 1. NOT doing tongue prayer for the Holy Spirit to intercede and fight forces in the unseen realm, or 2. NOT imitating Jesus's casting out the demon who tempts the believer in the first place, or 3. NOT fasting, which is key to break free from strongholds, 4. NOT converting to Pentecostalism so you receive 2nd baptism (filling in the Holy Spirit) so you receive power to fight temptation How should a Reformed believer respond to the above?
