2 Corinthians 12 Gossip in your church?

      16But be that as it may, I did not burden you myself; nevertheless, crafty fellow that I am, I took you in by deceit. 17Certainly I have not taken advantage of you through any of those whom I have sent to you, have I? 18I urged Titus to go,and I sent the brother with him. Titus did not take any advantage of you, did he? Did we not conduct ourselves in the same spirit and walk in the same steps?

Excerpts Commentary from Gills Exposition;
 Verse 16....to allure and draw the Corinthians into a good liking and opinion of the Gospel and of his ministry, and so caught them, and was the happy means of their conversion; but they are spoken in the person of the false apostles, charging him with a wicked and criminal craftiness, by making use of other persons in a sly underhanded way, to get this church's money, when he pretended to preach the Gospel freely; to which he answers in the next verse.

Verse 17.....I have sent to you: he desires them to name one single person of the many who came to them from him, that had received any money from them for him; or that they had any reason to believe he had employed for such purposes; and if they could not pitch on a single instance, they ought therefore to look upon this as a downright slander and calumny.

Paul had sent Titus and Luke to Corinth so he was defending them also with "Did we not conduct ourselves in the same spirit and walk in the same steps?"

Brethren we must be aware that Satan will send his minions amongst the flock to spread division and to turn us away from unity in Christ.
When you hear such talk YOU must realize several things;
1. Is it gossip?
2. Is it biblical?

1 Timothy 5:13 NASB: At the same time they also learn to be idle, as they go around from house to house; and not merely idle, but also gossips and busybodies, talking about things not proper to mention.

Don't listen to gossip, stop them in their tracks! Pray that the Holy Spirit gives you the words to speak. If they continue take it to the Elders of the church.
