If those who profess to believe present truth were indeed representatives of the truth, living up to all the light which shines upon their pathway, they would constantly exert upon others an influence for good, thus leaving a bright track heavenward for all who are brought in contact with them. But a lack of faithfulness and integrity among its professed friends is a serious hindrance to the prosperity of God's cause. Satan works through men who are under his control. The sanitarium, the church, and other institutions…have less to fear from the infidel and the open blasphemer than from inconsistent professors of Christ. These are the Achans in the camp, who bring shame and defeat. These are the ones who keep back the blessing of God and dishearten the zealous, self-denying workers in the cause of Christ. 4T 563
But if we walk in the light, as He is in the light, we have fellowship one with another, and the blood of Jesus Christ His Son cleanseth us from all sin. 1 John 1:7
