I once heard a preacher teach on where the Christian life "battles" are fought - our minds.
Let me assure you that external, physical "battles" do exist! I am NOT talking about persecution for our faith.
What I am talking about is the ongoing "chatter" in our heads playing the same deceptions since the dawn of time. I'm currently reading Crash the Chatterbox by Steven Furtick who has reminded me of some of the devil's ploys.
In the garden, the serpent asked Eve, "Did God really say..." Is that how he plants doubt today? Scripture says "If you confess with your mouth and believe in your heart that God has raised Him (Jesus) from the dead, you will be saved." Yet, we often are tempted to doubt that God really meant us individually.
We listen to the chatter of "Did God really me you? After all, you've done..."
Pastor Furtick pointed out that the devil's objective is to mess with our heads until we forget who we are in Christ. Think about when Jesus was tempted in the wilderness for 40 days. The devil came at Him with "If you are the Son of God, prove it by..." I'm paraphrasing here.
Jesus never answered with (again, my paraphrase) "Well, listen here, I am the Son of God!" He answered "It is written..." each time. He knew Who He is and would not debate that.
So when you are battling with "did God really mean that for me", remember who you are in Christ. You are loved by God and if you've been born again, you are forgiven. So when the chatter starts up in your mind, quieten it by "It is written..." and trust God that He meant what he said!
