This came to me while I was working on a sermon from Hebrews 1:1 – 4, on a point focusing on the identity of the Son of God.
Consider this parallel – when God the Father completed His creation work, He rested from that work. He continued to guide redemptive history and the Scriptures show His active involvement in shaping history and the lives of men. The Lord Jesus, after He had finished His work of atonement, He sat down at God’s right hand – resting from His work of redemption. He yet works – serving as our high priest and advocate, our protector and shepherd. And so it is with the third person in the holy trinity – the Holy Spirit worked during and after Pentecost to bring about the birth of the church, with many signs and miracles. Though the bulk of these miracles have ceased, the foundation of the church having been completed, the Holy Spirit continues His work of giving us illumination as we read the Scriptures; convicts the world of sin and the righteousness of Jesus. In each of these creation works and in all of the ongoing works, the three persons of the trinity are completely unified. Recall that the world was created through Jesus, and we read that the Spirit hovered over the waters during this event, as if giving birth. The Father chose those to be redeemed, Jesus atoned for them, and the Spirit has sealed them until the Day of Judgment. They each had a time of one-time creation work, followed by resting from that work, while continuing on, in unity, with other work required for our good – and their glory. This is the identity of the Son – completely at one with the Father and the Spirit.
