Two voices are speaking: Satan likes to come along and tell you, “Look at that sin you did 5 years ago! That was so bad! You are such a failure!” But Jesus, through God’s Word, tries to tell you that if you turn to Him, you will be forgiven (1 John 1:9), and your past will be forgotten: Isaiah 43:25, “I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins.”
You are faced with a choice: You can either listen to Satan’s lie that you are a failure, or you can listen to God’s Word that tells you that your past has been washed away and you are a new creature in Christ! 2 Cor 5:17, “Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.”
Whichever voice you listen to will crowd the other one out: If you have two dogs who fight all the time, and you can only afford to feed one of them, how do you know which one will win? The one you feed! The same is true in the spiritual realm. The more you listen to Satan’s lies and deception, the more he will build strongholds in your mind, and the more strongholds that go up, the harder it will be to hear God’s voice. The other side of the coin is true too… the more you feast yourself on the truth in God’s Word, the more it tears down strongholds and makes it harder for the enemy’s voice to penetrate your system.
If you listen to Satan’s lies that you are a failure, he will continue to feed you that lie, and it will grow into a stronghold (a lie that is believed, or an incorrect thinking pattern). Your feelings are quite often a direct result of your thoughts. If you think you are a failure, you will feel like one.
If you listen to your heaven Father, who is speaking truth to you through His Word, you will begin to tear down the strongholds in your life. When you meditate on the truth in God’s Word, it will become part of you, and before long, you will be feeling different, simply because you are exchanging lies of the devil for the truth in God’s Word. When you believe that your sins are forgiven, you can then allow your conscience to be cleansed from dead works by the blood of Jesus: Hebrews 9:14, “How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?”
