I couldn't help but think about faith as I watched this. It seems like as Christians there will always be blue holes that we come across. Obstacles that we need to face. Challenges that we need to overcome. Decisions that we need to make. A deep, dark abyss of the unknown. But we have to have faith because God knows, and He often leads us to such points in our life for a reason. We need to have faith in Him. We must have faith in the tools we have been given - the Word of God; prayer; the Holy Spirit; the church - so much is available to not only prepare us for such moments, but to get us through them. But the only way we will get through is to jump in. Trust God who sovereignly moves in our lives in every circumstance that we face - the good, the bad, the unknown. And when we do take that leap of faith we may be surprised at the unexpected beauty that we find. And He will always bring us back up for air - better for having faced and overcome the unknown - glorifying God for it. And it becomes a testimony to all about the wonder of having come to the brink, taking the plunge, and finding that God had beauty and purpose through it all.
If you're on the brink right now facing a blue hole of uncertainty - perhaps in your marriage, or your job, or your health - whatever the unknown is right now for you - jump in. Have faith. Trust God. There is unexpected beauty to be found and God will be glorified through it all.
