Isa 43:10 Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.

Now the skeptic chimes in:

You said God spoke to me, but I don't hear his voice.

You said that the Son testified, but I don't get it.

You said the Holy Spirit makes it make sense, but it's still gibberish.

And you say that Jesus testified in the flesh, but I wasn't there.

So how am I supposed to know?

Typically the answer is: You just have to believe, then you will know. I don't buy that answer either! Sometimes the answer is: Look at all the miracles! But the miracles were not intended to persuade non-believers. Not even Jesus's teaching was intended to do that. ^[1]

Imagine a crossword puzzle. There are clues for horizontal and vertical words that cross on shared letters. Got it? Now imagine that you could swap the letters consistently; replace every A with a W and ever B with a D, etc. Then by rearranging the clues, the puzzle still worked. Creating that puzzle might be difficult enough. But the one designing the substitution has to be different than the one who created the puzzle, and the clues all stay the same, just shuffled. That would seem pretty impossible even for a small puzzle. You would quickly claim that the one who made the puzzle must have designed it to be possible to be shuffled.

Now imagine that the words are not words, but sentences, and the letters are words. The same rules apply. But now there are over 23,000 sentences in play, and it must work for every single one. The clues remain the same and can only be shuffled. Oh yeah, and none of the clues make any sense until 400-4000 years later than when they were written, and they were written by more than 30 authors who didn't speak to each other or know anything about the subject matter.

If you were to observe that the claims were true, there could be no doubt that the puzzle was not created by the intention or accident of men.

As you studied in order to validate the claims... no you won't believe this, but it's true... you will start to hear the Spirit whisper answers to the riddles the same way he did for Peter.

This should not be a surprise! God wants you to know! And he will use every testimony he has given to man to make you know him. He seeks out every last lost sheep.
