Do not immediately follow one discourse with another, but let a period of rest intervene, that 6the truth may be fastened in the mind, and that opportunity for meditation and prayer may be given for both minister and people. In this way there will be growth in religious knowledge and experience.
(PH089 5.3)
Bible readings should be given, and believers and unbelievers should have an opportunity to ask questions on points not fully understood. Those who profess to be advocates of truth should ask questions that will bring forth answers that will shed light upon the present truth.
(PH089 6.1)
If any ask questions that serve to confuse the mind, and to sow doubt and questioning, they should be advised to abstain from such questioning, that others may be brought to Christ. We must learn when to speak and when to keep silent, and learn to sow seeds of faith, to reflect light and not darkness. Special meetings should be appointed for those who are interested in the truth, and who need instruction.
