This particular passage is about the fourth commandment that simply says, "Remember the Sabbath day by keeping it holy" (Exodus 20:8).
Pastor Blakey first said before Jesus was crucified the Sabbath was the last day of the week. After His death for Christians, the Sabbath is the first day of the week.
Then the pastor used the remainder of his time to explain why Jesus is God's gift of the Sabbath. He explained that Exodus 20:8 is an Old Testament scripture that is a foreshadow of what is revealed in the New Testament.
"Remember the Sabbath day by keeping it holy" is part of the Ten Commandments. The Old Testament laws do not save; however, they do point to a greater revelation.
Most people ignore that fourth commandment because they only think of it as a law to keep them from working. However, Rev. Blakey explained that God is serious about this commandment because He had Jesus in mind. He was thinking of the salvation and rest that would come about because of His Son's death on the cross.
The essence of this sermon is that salvation and rest are connected. When we come into the family of God, we also enter into His rest according to Hebrews 4:3. To remember the Sabbath is to remember our salvation. To remember our salvation is to remember the rest God wants us to have. God's lap is available for us to crawl up on and rest. In the midst of a storm, we can rest like Jesus did in the back of the boat.
Since Jesus is the Sabbath, we can rest while remembering the Sabbath.
