When Jacob finally begins the journey home with his household (which included all his servants, animals, and belongings) he is concerned that his previous actions toward his brother Esau will come home to roost.
He assumes that his father Isaac has likely passed at this point, and with Jacob nowhere to be found, Esau would have inherited everything. Enough to destroy his scheming homecoming brother.
Jacob devises a plan to try and save as many members of his household as possible should Esau and his 400 men have vengeance on their minds. But then he prays to God to save him. To keep him. To protect him.
It is unclear from the text whether Esau’s intentions changed between when he left and when he arrived, or whether Jacob’s newfound faith let him see how badly he treated Esau and so expected a strong retribution.
Either way, when Esau finally arrived, he greeted his brother with a smile and a warm embrace. Jacob’s fear were allayed. God had protected him just as He promised He would… just as Jacob had prayed.
When we have things before us that make us nervous, don’t just make a plan and do it under your own power. Invite God into every step. Let Him form your plans and let Him guide your work. His desire is to take care of his children.
Lay every plan at His feet and ask Him how He would like you to proceed. You won’t be disappointed with the outcome.
