Preach forgiveness of sins

Preach the Cross of Christ:
1 Corinthians 1:17-18: 17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect. 18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
Preach with power:

Preach the truth in love:
Ephesians 4:11-16: 11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; 12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ: 14 That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; 15 But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: 16 From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.
As I mentioned, these are only a few of the ways the Bible instructs us to preach. May God help us as we strive to follow His leadership in the ministry.
