Your road is in front of you, not behind.
God will never make you feel badly about your past. Once He forgives you, He forgets. The only ones who remember your past are you and the enemy, and you have control over both.
Whenever you start to feel guilty about sin you’ve already confessed, rebuke the guilt and claim your peace. Thank God for His forgiveness and enjoy your freedom. The enemy will always try to drag you back and get your eyes off of your future, but you don’t have to fall for it. As long as you are looking back, you’re not paying attention to what God is doing for you now. You’re prevented from growing, and you need to grow.
Guilt isn’t the only thing making you look back. Fear is also a trick of the enemy. Maybe you feel that you’re not ready for whatever God is calling you to. Rebuke that. If God has called you, then He will equip you and you’ll be fine. There’s nothing in your past that’s any better than your future in the Lord.
You have a destiny and a hope that is extraordinary in the kingdom. God has blessed you with a future that He’s waiting for you to walk in, so get started!
