“What does Scripture say? ‘Abraham believed God, and it was credited to him as righteousness.’”
Romans 4:3 NIV. https://www.bible.com/111/rom.4.3.niv
We are saved by grace through faith alone! (Eph 2:8-9)
We are not saved by rituals, nor the sacrifices we give, nor by anything that we think is good enough to earn God’s forgiveness.
The salvation we receive is a gift. We can’t earn it. Nobody can.
The reason the Old Testament saints are saved is because they believed God. That is, they believed all that God said to them in their past and present.
So when God talked about a future Savior, they took God at his word and believed him. I’m not saying that it was easy for them. But that is what ultimately saved them.
And it’s what ultimately saves us too. Taking God at his word and believing him.
Thank you God for saving me!
