Foundation Scripture: Ephesians 4:24 (Amplified Bible)
24And put on the new nature (the regenerate self) created in God's image, [Godlike] in true righteousness and holiness.
God holds nothing against any of us when we become His children by faith. When God forgives us, He trusts us as though we had never sinned. So when Satan comes around to try to remind me of my past transgressions/sins, I remind Satan that everything that has been charged against me came from him, and now everything I have- forgiveness, peace, and freedom- I have received freely from my Lord Jesus Christ!
As long as you remain on this earth, God has not completed His work in you. The Spirit of the Lord will help you discern when the chastening hand of God is upon you. But if it is Satan or his demons trying to tamper with your life or your Christian testimony, stand firm and resist him in the victorious power and name of the Lord Jesus Christ!
Jesus has said to us, "Whatever your need, just come to the throne of grace. Anything you need, you may have!" So why not believe Him and exercise the dominion He has given you?
Stay in the Word and Meditate daily!
