Hebrews 8:11

Will have to teach. By the old covenant, every Jewish baby was born into the covenant relationship and had to be instructed in his heritage. If they were not taught, they did not know God at all. But no one can be part of the new covenant without first knowing both the Father and the Son. The Book of Acts shows that all become part of this new covenant by faith in Christ, turning from sin, and being buried with Christ in the liquid grave. Because they will all know me. MacKnight sees in this the prediction of Isaiah 11:9. "Because the earth will be as full of awareness of the Eternal, as the water fills up the sea" (Zamenhof).
