'Preaching' in the Bible

For Christ did not send me [as an apostle] to baptize, but [commissioned and empowered me] to preach the good news [of salvation]—not with clever and eloquent speech [as an orator], so that the cross of Christ would not be made ineffective [deprived of its saving power].

For since the world through all its [earthly] wisdom failed to recognize God, God in His wisdom was well-pleased through the foolishness of the message preached [regarding salvation] to save those who believe [in Christ and welcome Him as Savior].

but we preach Christ crucified, [a message which is] to Jews a stumbling block [that provokes their opposition], and to Gentiles foolishness [just utter nonsense],

What then is my reward? [Just this:] that, when I preach the gospel, I may offer the gospel without charge [to everyone], so as not to take advantage of my rights [as a preacher and apostle] in [preaching] the gospel.

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].

But [on the other hand] the one who prophesies speaks to people for edification [to promote their spiritual growth] and [speaks words of] encouragement [to uphold and advise them concerning the matters of God] and [speaks words of] consolation [to compassionately comfort them].

Therefore, [unknown] tongues are [meant] for a [supernatural] sign, not to believers but to unbelievers [who might be receptive]; while prophecy [foretelling the future, speaking a new message from God to the people] is not for unbelievers but for believers.

If anyone thinks and claims that he is a prophet [a true spokesman for God] or spiritually astute [filled with and energized by the Holy Spirit], let him recognize that the things which I write to you are the Lord’s commandment.

and if Christ has not been raised, then our preaching is vain [useless, amounting to nothing], and your faith is also vain [imaginary, unfounded, devoid of value and benefit—not based on truth].
