They that are called to labor in the ministry of the word, are to preach sound doctrine,[1] diligently,[2] in season and out of season;[3] plainly,[4] not in the enticing words of man's wisdom, but in demonstration of the Spirit, and of power;[5] faithfully,[6] making known the whole counsel of God;[7] wisely,[8] applying themselves to the necessities and capacities of the hearers;[9] zealously,[10] with fervent love to God [11] and the souls of his people;[12] sincerely,[13] aiming at his glory,[14] and their conversion,[15] edification,[16] and salvation.[17]
