Calvin on God's power and resolve

I could fill this blog with incisive Calvin quotes (I use his commentaries in every sermon I prepare, unless something drastic happens). Perhaps I should! But anyway, here's a relevant one for believers today. Often those who stick to the Bible are told that they are "limiting God". Calvin:

"But it is idle, and unprofitable, and even dangerous, to argue what God can do unless we also take into account what he resolves to do" (comment on Luke 1:37 in Calvin's Gospel Harmony, volume 1).
