A Form of Godliness but Denying its power: A warning

There will be terrible times in the last days. ² People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents,ungrateful, unholy, ³ without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, ⁴ treacherous, rash, conceited, lovers of pleasure rather than lovers of God— ⁵ having a form of godliness but denying its power. Have nothing to do with such people.

2 Timothy 3:1-5 

Satan could not, as in former ages, keep God’s word from the people; it had been placed within the reach of all; but in order still to accomplish his object, he led many to value it but lightly. Men neglected to search the Scriptures, and thus they continued to accept false interpretations, and to cherish doctrines which had no foundation in the Bible. {GC 298.1}

The Second Coming— Great Controversy 370.2

“No man knoweth the day nor the hour” was the argument most often brought forward by rejecters of the advent faith. The scripture is: “Of that day and hour knoweth no man, no not the angels of heaven, but My Father only.” Matthew 24:36. A clear and harmonious explanation of this text was given by those who were looking for the Lord, and the wrong use made of it by their opponents was clearly shown. The words were spoken by Christ in that memorable conversation with His disciples upon Olivet after He had for the last time departed from the temple. The disciples had asked the question: “What shall be the sign of Thy coming, and of the end of the world?” Jesus gave them signs, and said: “When ye shall see all these things, know that it is near, even at the doors.” Verses 3, 33. One saying of the Saviour must not be made to destroy another. Though no man knoweth the day nor the hour of His coming, we are instructed and required to know when it is near. We are further taught that to disregardHis warning, and refuse or neglect to know when His advent is near, will be as fatal for us as it was for those who lived in the days of Noah not to know when the flood was coming
