To defy the Sunday laws will but strengthen in their persecution the religious zealots who are seeking to enforce them. Give them no occasion to call you law-breakers. If they are left to rein up men who fear neither God nor man, the reining up will soon lose its novelty for them, and they will see that it is not consistent nor convenient for them to be strict in regard to the observance of Sunday. Keep right on with your missionary work, with your Bibles in your hands, and the enemy will see that he has worsted his own cause. One does not receive the mark of the beast because he shows that he realizes the wisdom of keeping the peace by refraining from work that gives offense, doing at the same time a work of the highest importance.—Testimonies for the Church 9:232. ChS 163.4
When we devote Sunday to missionary work, the whip will be taken out of the hands of the arbitrary zealots who would be well pleased to humiliate Seventh-day Adventists. When they see that we employ ourselves on Sunday in visiting the people and opening the Scriptures to them, they will know that is useless for them to try to hinder our work by making Sunday laws.—Testimonies for the Church 9:232, 233. ChS 164.1
Sunday can be used for carrying forward various lines of work that will accomplish much for the Lord. On this day open-air meetings and cottage meetings can be held. House-to-house work can be done. Those who write can devote this day to writing their articles. Whenever it is possible, let religious services be held on Sunday. Make these meetings intensely interesting. Sing genuine revival hymns, and speak with power and assurance of the Saviour's love. Speak on temperance and on true religious experience.—Testimonies for the Church 9:233. ChS 164.2
Let the teachers in our schools devote Sunday to missionary effort. I was instructed that they would thus be able to defeat the purposes of the enemy. Let the teachers take the students with them to hold meetings for those who know not the truth. Thus they will accomplish much more than they could in any other way.—Testimonies for the Church 9:233. ChS 164.3
