It’s going to come by prophecy and the other gifts of the Spirit

For as we have many members in one body, and all members have not the same office: So we, being many, are one body in Christ, and every one members one of another. Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith; Or ministry, let us wait on our ministering: or he that teacheth, on teaching; Or he that exhortheth, on exhortation: he that giveth let him do it with simplicity; he that ruleth, with diligence; he that showeth mercy, with cheerfulness. Romans 12:4-8
