'Earnestly' in the Bible

Regarding this salvation, the prophets who prophesied about the grace [of God] that was intended for you, searched carefully and inquired [about this future way of salvation],

By obedience to the truth, having purified yourselves for sincere love of the brothers, love one another earnestly from a pure heart,

as newborn babes desire earnestly the pure mental milk of the word, that by it ye may grow up to salvation,
