Were you there when they crucified my Lord?
For all of the ages and all over the world we represent Bible characters like ourselves e.g. an Ethiopian Adam and Eve. "Were you there when they crucified my Lord?" You can be.
The Apostle Paul identifies the Rock of Psalm 95 vs 1 as Jesus. We need to hear his voice today and Hebrews stresses that it is still today. We will not find rest except in Jesus.
