It is difficult to have a civil conversation with "Christians" these days. They are so bound up in appearances and cliches they have no tolerance for honest open discussion with the Bible open and prayer for guidance from the Holy Spirit. Disagreeing is not a problem when both parties are seeking the Lord together for His truth.
Rarely do I have an opportunity to discuss anything in depth, everyone is too busy, too lazy and even disinterested in the things of the Lord.
2 Timothy 4:2-4 "…2 Preach the word; be prepared in season and out of season; reprove, rebuke, and encourage with every form of patient instruction. 3 For the time will come when men will not tolerate sound doctrine, but with itching ears they will gather around themselves teachers to suit their own desires. 4 So they will turn their ears away from the truth and turn aside to myths.…"
