Those whose business makes it necessary for them to come in contact with worldly men should stand constantly on guard, keeping strict watch over themselves and praying always, lest the enemy take them unawares. To those of His followers who are of necessity compelled to deal with worldlings, God gives grace according to their need. If they stand ever on guard, special wisdom will be given them when they are obliged to be in the company of those who do not respect the Lord Jesus Christ. Their every transaction is to reveal the fact that they are Christians. They are to be kind and courteous in all that they say and do, showing that they are under the control and discipline of God, that they are serving the Lord Jesus Christ. (HP 311.2) MC VC
