"Certainty is the mark of the common-sense life: gracious uncertainty is the mark of the spiritual life." - Ozzie (Oswald Chambers) We are certain of God: we are uncertain of what will happen next. There is much to be said of faith and the spiritual life as it applies to certainty.
We are so obsessed with certainty. Is it really all that necessary? Well, its not if you are living a life of faith...the spiritual life. The spiritual life is not one of certainty. The moments I am so uncertain of what would happen next are the moments my faith is stretched and made stronger.
When you stretch your muscles they grow. They do not necessarily grow stronger and bigger, but they do grow more flexible, which allows them the ability to grow stronger in time.
So here I am a man in need of flexibility. I am a man in need of faith...because I am certainly uncertain. These are now the times of becoming more flexible, and that flexibility makes strength more available. That ability ultimately leads to strength.
