'When Jacob saw that there was grain in Egypt, Jacob said to his sons, "Why do you look at one another?.... Indeed I have heard that there is grain in Egypt; go down to that place and buy for us there..." (Gen.42:1,2)
Oftentimes, God uses circumstances to guide us. But, He always guides to only the good, never into evil. In this incident, Jacob is being constrained towards the only logical and practical option left. But, this constraint was what God actually used to get them to Egypt according to His plan. When we trust in divine sovereignty, we can give thanks to God in everything. If we feel confused about some decision, we can ask, "What is the good, practical and God-pleasing final option or solution to this issue?" We don't need to just stand looking for some answer or for someone to do something. Just take a decision.
