Abraham: Who, Where, How, Why and When?
Abraham was called out of Ur by God, as He calls people today. The Christian is similarly called to leave their old life behind, and as Abraham was promised an inheritance, the Christian will inherit a new heaven and new earth. He had been cowardly and makes a sacrifice. Atonement is gruesome, all the way to Calvary.
