Ignorance is a veil, it is a mantle over each head of each person who has decided to remain submerged in it and not swim in deeper waters. God was pleased that those things that the ancients could not know are revealed to us through the Gospel of our beloved Lord Jesus Christ.
The Bible is God’s revelation to us, we all have free access to it, and we can ask that His Spirit allows us to understand it. But sometimes we prefer to continue with the veil, and we only become those kind of people who blindly believe in what other people say, without examining through the Scriptures if what they say is true.
There was a time that the church lived in darkness, with a veil, because they couldn’t even read the Bible in their language, but God raised men who swam in deeper waters so that this truth could reach everyone.
