The scripture, foreseeing ... faith, preached the gospel

Because God's promise to Abraham was written in the scripture before Christ fulfilled the promise, the scripture is like someone who knows the future before it happens and who preaches the gospel. Alternate translation: "In the scripture, God showed before it happened ... faith, and he presented the gospel" (See: rc://en/ta/man/jit/figs-personification)

In you

The word "you" refers to Abraham. Ultimately God would bless the nations through one of Abraham's descendants. Alternate translation: "Because of you" or "Through you"

all the nations

"all the people-groups in the world." God was showing that his plan of salvation was not only for the Jewish people, but for both Jews and non-Jews.
