Blue  v23-24   Ch 17  1 Kgs

v23  Elijah picked up the child..."Look, your son is alive!"

v24  Then the woman said to Elijah, "Now I know that you are a man of God and that the word of the LORD from your mouth is the truth."

She had to see it to believe it.  She wasn't the only one who had this problem.

Jn 6:30  ...they said to Jesus, "What sign will You perform then, that we may see it and believe You?  What work will you do?

Both had to see it to believe it only that's after the fact;  in pattern with Jn 20:29 it is more blessed to believe without seeing because faith is exercised and every time we operate in {2 Cor 5:7} faith to promote life it will send message back to God that we believe He is as Good as He really is, that He is Worthy to be trusted.  It's a great way to build the relationship with Him~
