'Cultivate' in the Bible
For through the authority graciously given to me I warn every individual among you not to value himself unduly, but to cultivate sobriety of judgement in accordance with the amount of faith which God has allotted to each one.
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].
So then, my dear ones, just as you have always obeyed [my instructions with enthusiasm], not only in my presence, but now much more in my absence, continue to work out your salvation [that is, cultivate it, bring it to full effect, actively pursue spiritual maturity] with awe-inspired fear and trembling [using serious caution and critical self-evaluation to avoid anything that might offend God or discredit the name of Christ].
Practice and work hard on these things; be absorbed in them [completely occupied in your ministry], so that your progress will be evident to all.
