In the Father’s House–Eternity (v. 6). As the shepherd lay each night at the door of the sheepfold, he looked back over the day and gave thanks that the Lord had blessed them with goodness and mercy. As an old man, David looked back over his long life and came to the same conclusion. Despite his sins and failures, he had been followed by goodness and mercy, which is the Old Testament equivalent of Romans 8:28. “Surely” means “only.” As David looked ahead, he knew he would be in heaven–the Father’s house–forever. This isn’t a reference to the temple, because the king didn’t live in the temple. Furthermore, nobody could live there or anywhere else forever. Jesus used this vocabulary to speak about heaven (John 14:1-6). The things that perplex and disturb us today will all be clear when we get to heaven. We will look back and see “only goodness and mercy.” Under the old covenant, the sheep died for the shepherd, but under the new covenant, the Shepherd died for the sheep–and we shall meet our Shepherd in heaven! “For the Lamb who is in the midst of the throne will shepherd them and lead them to living fountains of waters. And God will wipe away every tear from their eyes” (Rev. 7:17 nkjv).
