The "marks" of grace-based prayer are defined as a shift from "praying for victory" to "praying from victory". This approach emphasizes that believers should not beg God to do what He has already accomplished through Christ. 

Key marks of grace-based prayer include:
Praying from Victory: Instead of asking God for peace or victory, you acknowledge that you already possess it and pray from that completed state.

Rooted in Identity: Prayer begins with who you are in Christ (righteous, complete, and a son/daughter) rather than your past behavior or performance.

Dependence on the Finished Work: It focuses on the "finished work" of Jesus, meaning you don't try to get God to move; you move because He has already moved.

Expression of Gratitude: Since the prayer assumes the answer is already provided in the spirit realm, it is characterized by constant thanksgiving.

Led by the Spirit: Grace-based prayer is fueled by a relationship with the Holy Spirit, who helps the believer receive God's favor.
