They are so positive that no one who desires to understand his whole duty to God needs to make any mistake in the matter. If men offer any excuse as to why they do not perform this duty, it is because they are selfish, and have not the love and fear of God in their hearts. Those who plead that they cannot understand this plain and decisive statement—which if they are obedient, means so much to them, in blessings which will be received, when even the windows of heaven will be opened, and blessings poured out to overflowing—are not honest before God. Their excuse that they do not know the will of God, will be of no avail for them in the great day of judgment. PH166 19.1
