Galatians 5:10 I have confidence in the Lord that you will take no other view than mine, and the one who is troubling you will bear the penalty, whoever he is.
Though at many times the apostle Paul seem to have the appearance of roughness and a severe attitude, he now displays a change in attitude, a quit confidence. this should be every evangelist attitude, and quit confidence. That comes by knowing that all we can do is till and water, but it is God who gives the increase. My of Christians lack this confidence, they are under the false belief that man has a spark of good in them, and if they use the right words they can fan that spark. They will never feel confident that they said the proper thing, even if that person to whom they were sharing with responds, if they respond in their own power it is for naught. I have said this many times before the natural man is unable to respond, see they are dead to the spiritual things of God. Paul confidence comes in the fact that He knows God is the author and finisher of our faith and what God begins He always finishes. Paul knows if He is preaching what God has called Him to preach, He Paul can rest in that confidence. It is a peaceful and confident attitude that marks a Christian who understands that it is God who draws sinners to Christ (John 6:44) It is the Holy Spirit that quickens the sinner giving them eyes to see and ears to hear, that they may embrace the savor who died for their sins. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.” (Acts 4:12) Woe is the ones that trouble those whom God has called, by trying to place undue laws, and regulations on them, they answer to only Satan, and they shall share His judgement. So all that Paul has gone through from the beginning of Galatians to now, we see a confident Paul, know that He preached the truth of Scriptures as commanded by God, and can have confidence and peace knowing that no-one can pluck them from the hand of God. Paul knew full well that God predestines, God calls, God justifies, God Glorifies. Now that is confidence.
