The Devil who could speak and angels fell, never overrate yourself in front of such being. Christ is only chance that you stand, you are not that strong. It doesn't matter if you were born in a Christian home. "It is Christ in us the hope of glory". This is our only chance.
As a believer we have all have strange thoughts in our minds. We have strange questions like, Who is God? Where is Go? What is the proof that God exists? Who was there when Jesus came? When people die where did they go to? Your head will start spinning with lost of questions. That is why you need Bible study.
What the devil is trying to present is the fact that you have those questions, it means that you are smart. You are asking this questions because you are a smart Christian. The fact is that the reason you were asking these questions, you were not laid on a foundation and you were not taught. You need more of Bible Study and prayers so that devil will not fill the space of your heart with questions that will take away the faith you have in God.
