Within the sovereignty of God which carries the idea of independent autonomy lies the concept of God’s providence which sees God as providing continual care over His creation. Merrill Unger states of God’s providence: “That God could create the world and then forsake it is inconceivable in view of the perfection of God. Accordingly, in the power and wisdom and goodness of the Creator declared in the Scriptures, we have the pledge of constant divine care over all parts of His creation (The New Unger's Bible Dictionary). So it comes as no surprise that Joseph would claim in Gen 50:20 “you meant evil against me, but God meant it for good…”
To understand this concept properly we must look at the word “meant” translated ‘chashab’ which carries the idea of something that is interwoven. Now it would be a mistake to see God’s intent as being interwoven with that of man’s so that they struggle against each other to a particular outcome. Rather it is better viewed as the interweaving of “human events” by God the master weaver to obtain the outcome fitting to His purpose. This means the events of Joseph’s life, his family, all of
, as well as the famine were woven as a tapestry for the expressed purpose of furthering God’s purposes on earth or “to preserve many people alive.” It is this preserving interweaving that is expressed by Isaiah in Isa 45:7 where he declares that it is God who causes “well-being” as well as “creating calamity.” Egypt
So that ultimately there is only one will, that being God’s and how He works His sovereign will and still allows for the free will of man is a mystery He has not chosen to reveal.
