Time is like a zipper. The past has been determined, while the future remains open. The present is that very interval of interaction between what is yet to be into becoming what has been. For our interaction with the eternal God to be at all meaningful, He must necessarily experience time sequentially as we do since its creation. This profoundly implies the openness of the future being guided by God, if we follow His will, or else a deviate from it. In this openness of the future, along with our free-will, it is therefore possible and even likely that what God wills for our life and what actually happens may be two different things altogether. The zipper-like nature of time and the gracious merciful nature of God continuously interact, so that even if we disobey and change routes God’s will is powerful enough to meet us in our current “fork in the road” to guide us again in His calling–or even create an entirely new calling.
The sovereignty of God, then, is shown as being even more powerful–He is after all omnipotent. To create an open system for a creature with a profound free-will, guiding the future requires not the stringing of a puppet, but the conviction onto the heart of that creature in and through relationship into a loving bond where the created creature relinquishes his own sovereignty, gifted by the Creator, into the hands of His master. This is what it means to be clay in the Potter’s hands.
