Editing Isaac (section)

===New Testament===
The [[New Testament]] states Isaac was "offered up" by his father Abraham, and that Isaac blessed his sons.<ref name="Easton"/> Paul contrasted Isaac, symbolizing [[Adiaphora#Christianity|Christian liberty]], with the rejected older son Ishmael, symbolizing slavery;<ref name="EoR-Isaac">''Encyclopedia of Religion'', ''Isaac''.</ref><ref>{{bibleverse|Galatians|4:21–31|KJV}}</ref> Hagar is associated with the [[Sinai Peninsula|Sinai]] covenant, while Sarah is associated with the covenant of grace, into which her son Isaac enters. The [[Epistle of James]] chapter 2, verses 21–24,<ref>{{bibleverse|James|2:21–24|KJV}}</ref> states that the sacrifice of Isaac shows that justification (in the [[Johannine]] sense) requires both faith and works.<ref name="EoC-Isaac">''Encyclopedia of Christianity'', Bowden, John, ed., ''Isaac''.</ref>

In the [[Epistle to the Hebrews]], Abraham's willingness to follow God's command to sacrifice Isaac is used as an example of faith as is Isaac's action in blessing Jacob and Esau with reference to the future promised by God to Abraham.<ref>{{bibleverse|Hebrews|11:17–20|ASV}}</ref> In verse 19, the author views the release of Isaac from sacrifice as analogous to the [[resurrection of Jesus]], the idea of the sacrifice of Isaac being a prefigurement of the sacrifice of Jesus on the [[Christian cross|cross]].<ref>F.F.
