I've considered these things my entire life, though I wasn't able to understand them until I was 39 years old and born again. Christ completes His church when He returns. We have His promises, we have His Spirit, we have His word.
His word says:
11 When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. 12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known.
13 And now abide faith, hope, love, these three; but the greatest of these is love. 1 Corinthians 13:11-13
