While there are many smart people, including Biblical scholars, no one knows it all. God reveals bits and pieces to us through study, but we won’t know everything until we see Him after our earthly life is over and eternity begins. In 1 Corinthians 13:12 Paul says it perfectly, Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. I love my time on this earth and I full expect to live each moment to the fullest. But I cannot wait to see Jesus face to face for the first time. It will be and amazing moment to say the least.
