God's Unalterable Purpose

Why did Isaac bless Jacob even though Esau was the eldest? How is Jacob a type of Christ's Church? Who does Rebekah represent in leading Jacob to the blessing? Who MUST the Father see in order to grant His blessing of redemption? Why should the chosen ones need not worry that the Father would see them (THE sinner) and not the Substitute (Christ)? Where is true acceptance found? Why was Jesus hated by men and numbered among transgressors but LOVED above all by the Father? How can a vile sinner like Jacob be accepted by the Father? What happens to those who come before the Holy Father in their own merit? Where is life eternal? Who can take the accepted away from the Father? Who is the woman's promised Seed and when was the promise made? Has God's justice been satisfied yet?
