Sing to the LORD, bless His name; Proclaim the good news of His salvation from day to day. Psa 96:2
Do we realize that the gospel – the good news of His salvation – did not appear out of thin air with the birth of Jesus Christ, but that there has been one gospel, one good news of the LORD’s salvation from Genesis on? In Gen 1, before man or any living thing was created upon the earth, God placed the stars in the heavens to serve as witnesses, it says in Hebrew.
To what do they bear witness? The good news of His salvation, for one:
The heavens declare the glory of God;
And the firmament shows His handiwork.
Day unto day utters speech,
And night unto night reveals knowledge.
There is no speech nor language
Where their voice is not heard.
Their line has gone out through all the earth,
And their words to the end of the world. Psa 19:1-4
The constellations themselves were taught to Seth by God, and they proclaim the good news of His salvation. The Tree of Life was placed in the garden, which proclaimed the good news of His salvation. Enoch walked with God, and did not die, which proclaimed the good news of His salvation. Noah built an ark, which proclaimed the good news of His salvation. Abram circumcised his son, then offered him on Mount Moriah, which proclaimed the good news of His salvation. The Israelites painted the blood of the Passover Lamb on the doorposts of their houses, which proclaimed the good news of His salvation.
In many multiple and diverse ways, God has been proclaiming the good news of His salvation from the foundation of the world. The good news has not changed from then till now. David knew the good news of His salvation — he was not saved by keeping the Torah perfectly, for he committed adultery and murder — and he encouraged Israel to proclaim it!
