There is a song titled "Oferta de amor" by Ministério Koinonya de Louvor. You will be able to find it easily in Youtube.
The question is about the following part of the song:
Pois pra Te adorar foi que eu nasci
Cumpre em mim o Teu querer
First, how come the words "foi que" appear in this contexts? It just doesn't make sense to me.
Second, regarding "Cumpre em mim o Teu querer", I guess the word "querer", which is an infinitive, should have some special meaning together with the verb "cumpre". But again, it just doesn't make sense.
Please help me understanding this part of the song. (The rest of the song was relatively easy to understand.)
