Moroni 7:25

Wherefore, by the ministering of angels, and by every word which proceeded forth out of the mouth of God, men began to exercise faith in Christ; and thus by faith, they did lay hold upon every good thing: and thus it was until the coming of Christ.

So through angels helping and through every word from God’s mouth, people started to have faith in Christ. Through this faith, they held on to every good thing. This happened until Christ came.
