This has the false appearance of being from the Gospel of Matthew, ch. 7 -- the section called the "Sermon on the Mount." The Latin translation of the original Greek of the equivalent phrase there is actually, "quaerite et invenietis," rendered traditionally in English as, "seek and ye shall find."

The grammar of the Latin phrase you offer is different from "quaerite et invenietis." Instead of the imperative (command) form, QUAERITE, joined with ET ("and") to the main future-tense verb, your sentence shows QUAERENDO, "By seeking; If you seek".

But "seek" is becoming rather archaic in ordinary conversation, and "ye" fell out of conversational use about 350 years ago. Latin also commonly omits direct-object pronouns, just as it usually omits subject pronouns. So I've tried to use up-to-date ordinary English in my rendition, replete with object pronouns.
