That title is filled with some questions. My first thought is, "Isn't certainty a good thing?" When I was younger, I think I had a whole lot more certainty about things, especially in my teenage years. As I've gotten older, I have become much more comfortable with mystery.
It seems that there is a thread throughout scripture that lends itself to the idea of trust in uncertainty. God is constantly reminding us about the need for trust. The struggle of humanity has always been the desire to go our own way. We tend to put our trust in tangible things such as jobs, money, relationships, and governments. All the while suffocating on stress, need for acceptance, and worry. We know that God says our needs will be taken care of well behind the "birds of the air" and the like (Matthew 6:26). The real issue is, we want more than our needs. We want more. We want comfortable and well beyond. We want certainty to the point that it becomes and idol. Certainty becomes the thing that we strive for and we seem to not care about the means in which we get there. For us, the sovereignty of God is always in question. The interesting, yet sad thing is, the sovereignty of God has been in question from the beginning. Great men and women throughout history have questioned God and his ways and purpose.
May we be a people that trust, more fully, each day. May we be ok with uncertainty. As Romans 15:13 says, "May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit."
