Firstly, there's obedience. He tells you to do something obscure, odd, difficult or impossible. You can choose whether or not you want to obey, but if you don't, you can bet two things. 1) You're going to stay where you are for a while longer and 2) You're going to take the test again.
Another test that God uses is on our patience. He tells us to wait. Or to make things a bit trickier, He makes us wait by not telling us anything at all. Our job is to keep strong in prayer while waiting for Him to give us the answer. The faster we cling to God in this difficult time, the better.
These tests can be hard at the time, but there's something wonderful about them. God gives us more than one chance. And when we do succeed, the rewards a bountiful blessings.
Unfortunately, though, I can't really say much more on this topic. I can't really give advice, because how one makes these choices is highly personal. All I can do is ask you to keep what I told you in mind. It might help you to decide the right way when your next test comes up.
Oh and... one more thing. With your blessings, you'll get more tests for chances at more blessings.
Thank You for giving me so many wonderful chances to grow as a person. I relish the chance to find out more about who I am and what You want me to do, but know that the tests aren't always easy.
Please guide me, Lord. Please give me the discernment to know when You are testing me so that I can be fully prepared to do what I need to do.
I pray this in Jesus's name.
