At the time of Genesis 49, when Jacob prophesied concerning his twelve sons with blessing, he was a God-man, a man filled, constituted, permeated, and even reorganized with God; whatever he thought was God’s thought, and whatever opinion he expressed was God’s opinion—cf. 1 Corinthians 7:10, 12, 25, 40.
In order to prophesy with blessing, we must know God, the desire of God’s heart, and the purpose of God; we must know people; that is, we must know the actual situation of every person involved; we must be full of the riches of Christ; we must have a strong, active spirit.
