His character should be spotless so that he will not cast reproach upon the cause of the Lord Jesus Christ. He should pay his bills and not be a debt dodger. He may have some credit accounts, but the bills should be paid on time. I do not believe that is saying it is sinful to have a charge account, but you should seek to pay bills on time and not over-obligated yourself financially. He must be careful around the younger women in the church lest people start rumors that would hinder his ministry in the local church.
People love to start women tales on preachers.
The man of God should be where if that starts, he can honestly say it is not so. Folks who start such kinds of things, if they are just cruel gossip and hearsay, they should be brought before the church and be disciplined. I believe it means just what it says and says just what it means. One wife unless the first wife dies. God s plan for marriage is one man and one woman for a lifetime, and He has never changed that preference of His and never will.
