The prophecy concerning the sufficiency of Asher typifies the enjoyment of Christ as the rich provision of life for fighting and building (Genesis 49:20; Deuteronomy 33:24-25). Jacob’s prophecy in Genesis 49:20 and Moses’ blessing in Deuteronomy 33:24-25 show the sufficiency of Asher, coming after the recovery with Gad; Asher was blessed with rich food, with the rich provision of life. Just as Asher was the one “dipping his foot in oil,” we can “walk in oil” by enjoying the bountiful supply of the Spirit of Jesus Christ for our daily walk. When we enjoy the Lord daily as our rich provision of life (“as your days are, so shall your strength be”—Deuteronomy 33:25b), He becomes our secret of sufficiency for us to be content in any situation (Philippians 4:11-13; Psalms 23:1). The issue of such a rich provision is the enjoyment of absolute rest with peace, strength, security,and sufficiency. (2014 Summer Training, msg. 11 outline)
