What if it were true, that at the end of a particular rainbow, if you found that end, you would find an unbelievable amount of money? What kind of trouble would you go through in order to find the end of this rainbow? What expense would be involved timewise? If you knew that it were true, would you go after this rainbow to find this money? Would you count the cost of this adventure?
Here is a more believable question: What if you were made aware of a piece of property that had buried in it somewhere, a container with billions of dollars? How diligent would you be to secure that piece of land before anyone else gets to it?
I believe God wants to ask us the same thing. How much are we willing to give up in order to know Him? I am not talking about giving things up or letting go of things just for the sake of giving things up or letting go of them. When we come to God, we all have things we have to let go of. Some of those things, God will set us free from, so we can see Him and know Him better. What will be the cost to us, for us to know God?
For some, it would mean leaving family behind. There are some families who will not tolerate Christianity, and for those who come to Christ from those families, they will be called to leave them. For others, it could mean a job or career. Some careers involve pornography, while others are safer, but still an obstacle to knowing God. Some will have to let go of friends (they might be the ones letting go first), and activities that keep us in darkness.
The goal is not to just do something to make God happy. When we do such things, it is called, 'legalism'. The goal is God Himself. What will you leave behind or have to let go of, in order to know God, to see God, and to hear His voice? Would you go through as much trouble as you would for the money as you would in order to know Him? How expensive will it be for you to know God? Are you willing to pay the price? Are you willing to let go of your treasures to know Him?
"Jesus said to them, “Truly, I say to you, in the new world, when the Son of Man will sit on his glorious throne, you who have followed me will also sit on twelve thrones, judging the twelve tribes of Israel. And everyone who has left houses or brothers or sisters or father or mother or children or lands, for my name's sake, will receive a hundredfold and will inherit eternal life." Matthew 19:28-30 ESV
