We do this everyday though. With every choice we make. Even in the slightest of situations we have to make a choice then jump right into our choices and deal with whatever consequences we meet.
Lets say your decision brings you to a cliff because its a big choice. You look down and see the crystal clear waves but there is a sign next to the edge that says piranhas. So hold your breath, look over the edge and fall like an idiot face first into the icy abyss. Way to go. You know that the decision will most likely end in injury or your ultimate doom but you go anyway because lets face it the drop down was really fun. Sure once you hit the lake it'll be horrible but thats all apart of growing up and experiencing life right?
WRONG. So now that you've waisted time getting bitten up and hurt you can climb out of the lake and up to the next cliff and try again. But this time you might actually look before you jump. (This goes with choosing which relationships we get in, obedience with your parents, and where/how you go/perform in school, etc.)
There are big decisions like cliffs that shape who we are and leave us with some nice scares, but there are also little decisions like jumping into a pool from the side that affect how we get to the bigger decisions. And then when we jump and make the right decision we get to focus on how fancy our jump is and try to make the biggest splash!
So think about where God wants you using your faith and jumping in and where God is telling you to steer clear. You won't regret your choices and have your butt bitten by sharks if you look to him for every choice you make.
