1 Cor 1:17 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.
Yes, Paul is an example of the correct way of witnessing. Not talking about salvation by water baptism but of the cross, the gospel message. Not by man's wisdom but by the word of God. His truth spoken by the Spirit of God. Oh how the enemies of Christ oppose the word of God. They oppose and discredit the one who speaks the word. They want you to use your own thoughts and opinions, which are easily mocked. Do not try to justify yourself by your own words, instead speak the powerful word of God. Don't be fooled by satan's tactics, continue to speak God's word to those who will hear. Keep the focus on Christ crucified. (I Cor 1:23)
1 Cor 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
The blood shed by Jesus on the cross of Calvary paid for our sins. We must believe this and receive Jesus as our Lord and savior. There is no other way that our sins can be forgiven.
Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
The worldly wise think they know more than God; by doing this they become fools because they do not fear God nor respect his commands.
Psa 14:1 To the chief Musician, A Psalm of David. The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
We are saved by the power of God through faith in Jesus' name.
John 17:1 These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
John 17:2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
1 Cor 1:19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
1 Cor 1:20 Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world?
The world's wisdom is always changing but the word of God endures forever. To argue with God only shows your unbelief. We must accept God's word by faith for It is truth. Many prophecies have come about to prove the truth of God's word. God stands behind his word, It is truth and those who believe are filled with the Spirit of truth.
2 Tim 2:15 Study to show thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
2 Tim 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
1 Cor 1:21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
We believe and are saved by faith in Jesus Christ. We are to share this truth and salvation by preaching and witnessing to the lost.
Rom 10:13 For whosoever shall call upon the name of the Lord shall be saved.
Rom 10:14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
Rom 10:15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
Rom 10:16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
Rom 10:17 So then faith cometh by hearing, and hearing by the word of God.
We are called to deliver people from satan's bondage by preaching the cross. There is no other way to be saved but by faith in the Lord Jesus Christ.
