Jesus journeyed toward Jerusalem, in Luke chapter 13, for His Loving Sacrifice on the Cross and He invites us to Strive alongside Him in His establishing the Heavenly City with Justice and Righteousness. The Prophet Isaiah, in chapter 28, reminds us that the Lord is the precious cornerstone. The grace of the cornerstone is available when we participate in that grace and holiness but is lost if we reject Him as the Letter to the Hebrews describes Esau had done in chapter 12.
