"The Sins of Babylon I saw that since the second angel proclaimed the fall of the churches, they have been growing more and more corrupt. They bear the name of being Christ's followers; yet it is impossible to distinguish them from the world. Ministers take their texts from the Word of God, but preach smooth things. To this the natural heart feels no objection. It is only the spirit and power of the truth and the salvation of Christ that are hateful to the carnal heart. There is nothing in the popular ministry that stirs the wrath of Satan, makes the sinner tremble, or applies to the heart and conscience the fearful realities of a judgment soon to come. Wicked men are generally pleased with a form of piety without true godliness, and they will aid and support such a religion. EW 273"
"For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;"
Both passages discuss a time when people will turn away from sound doctrine and seek teachers who will tell them what they want to hear. EGW's passage elaborates on this by describing ministers who preach 'smooth things' that don't challenge the 'natural heart.'
"Said the angel, “Nothing less than the whole armor of righteousness can enable man to overcome the powers of darkness and retain the victory over them. Satan has taken full possession of the churches as a body. The sayings and doings of men are dwelt upon instead of the plain, cutting truths of the Word of God. The spirit and friendship of the world are at enmity with God. When the truth in its simplicity and strength, as it is in Jesus, is brought to bear against the spirit of the world, it at once awakens the spirit of persecution. Very many who profess to be Christians have not known God. The natural heart has not been changed, and the carnal mind remains at enmity with God. They are Satan's faithful servants, notwithstanding they have assumed another name.” EW 273.2"
"Put on the whole armour of God, that ye may be able to stand against the wiles of the devil."
EGW directly references the concept of putting on the 'whole armor' to overcome darkness, which is a clear allusion to Ephesians 6:11.
