All-Knowing God?

This week at BNX we continued to look at the Sovereignty of God by discussing the idea that God is "all-knowing". This is one of those things that I think most of us have no trouble buying into...at least in our heads and in our words. After all, who would ever say that they don't really believe that God knows everything. But do we really think about what that means, and more importantly do our actions really say that we truly believe it?
I shared from Genesis 12-16 where we see the account of Abram. He was given a promise of great blessing from God in 12:1-2. God tells Abram, a man with no son, that he was going to be the father of a great nation. What an incredible promise from God! And I am sure that Abram was pretty excited about this. Over time, that excitement turns to anxiety as Abram begins to question and doubt this promise as he does not "know" how God plans to make it happen...especially for an old man with no son. In chapter 15:2-3 Abram decides he needs to explain his situation to God...as if He did not really know the whole scenario? But God tries to give him a little reassurance and tells him that he will not only have a son but that his offspring will be so abundant it will be like trying to count the stars. Now that is a pretty serious promise! But as more time passed, and Abram and his wife Sarai got older, they just did not know how God would be able to keep his promise...they forgot that God knew exactly how He was going to do it. In chapter 16 They decided to take matters into their own hands rather than trusting in God's Sovereignty. They decided that they "knew" a better way. Sarai gives Abram her maidservant Hagar, to bear them a child. This one poor decision on their part is still impacting us today. Through his own plan (along with Sarai) Abram did bare a son, Ishmael, who is the father of Islam. They were not able to rest in the sovereignty of God and trust in the fact that God did "know" how He would achieve his promise.
We often have those same struggles. When we do not know how God plans to do something...we tend to doubt or at least question Him. When he tells us that we are to be His witnesses to the ends of the earth, we want to know step by step what that looks like. Where should we be going, when, with who, what safety protections will we have? We want to "know" all the details. Doesn't that reflect that we don't really trust that God "knows" all those details? Or maybe we want to do what we "know" will help and we just send our money. And this is a great thing...unless God wanted us to GO. I wonder if our lack of faith in the Sovereignty of God could have similar results to Abrams lack...and impact generations of people to come?
