'Cultivate' in the Bible

Now I entreat you, brethren, in the name of our Lord Jesus Christ, to cultivate a spirit of harmony--all of you--and that there be no divisions among you, but rather a perfect union through your having one mind and one judgement.

But earnestly desire and strive for the greater gifts [if acquiring them is going to be your goal].And yet I will show you a still more excellent way [one of the choicest graces and the highest of them all: unselfish love].

Pursue [this] love [with eagerness, make it your goal], yet earnestly desire and cultivate the spiritual gifts [to be used by believers for the benefit of the church], but especially that you may prophesy [to foretell the future, to speak a new message from God to the people].
