"I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom; Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine. 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; And they shall turn away their ears from the truth, and shall be turned unto fables. But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry." - 2 Timothy 4:1-5
We must not have a sensational religion, which has no root in truth. Solid instruction must be given to the people upon the reasons of our faith. They must be educated to a far greater extent than they have been in the doctrines of the Bible, and especially in the practical lessons that Jesus gave to his disciples. The believers must be impressed with their great need of Bible knowledge. There must be pains-taking effort to fasten in the minds of all, the solid arguments of the truth; for every one will be tested, and those who are rooted and grounded in the work of God will be unmoved by the heresies that will arise on all sides; but if any neglect to obtain the necessary preparation, they will be swept away by errors that have the appearance of truth.
I have been shown that but a small number of the people in our churches know for themselves what constitutes the third angel's message ... This fact should enable us to realize the need of Bible classes. Instruction should be given on the subjects of faith and Christian experience, and there should be seasons of earnest prayer. - Gospel Workers, p. 92, E. G White
