Emotions are not the only things that influence our faith and often keep us from what godly reason tells us is true, particularly in spiritual matters. Emotions are one factor, and they were certainly a factor in Jacob’s strange turmoil when he was told that Joseph was alive and ruler of all Egypt. At first Jacob refused to believe it.
"It is enough."
I am sure that Jacob did not see the whole picture. I think that some of that had to be supplied by Joseph when Jacob got there into Egypt. He did not see the whole picture, but he was at least comforted. He was consoled. There was encouragement that came into his life.
