The worker in a foreign field must carry in his heart the peace and love of heaven; for this is his only safety. Amid perplexity and trial, discouragement and suffering, with the devotion of a martyr and the courage of a hero, he is to hold fast to the hand that never lets go, saying, “I will not fail nor be discouraged.” He must be a close Bible student, and should be often in prayer. If, before talking with others, he will seek help from above, he may be assured that angels of heaven will be with him. At times he may yearn for human sympathy, but in his loneliness he may find comfort and encouragement through communion with God. Let him be cheered by the words of the Saviour, “Lo, I am with you alway, even unto the end of the world.” [Matthew 28:20.] From this divine Companion he will receive instruction in the science of soul-saving. GW 469.1
Energy and self-sacrifice are needed in the missionary field. God calls for men who will push the triumphs of the cross; men who will persevere under discouragements and privations; men who have the zeal and resolution and faith that are indispensable in the missionary field. By persevering toil and a firm trust in the God of Israel, resolute, courageous men will accomplish wonders. There is scarcely a limit to what may be achieved if the efforts made are governed by enlightened judgment and backed by earnest endeavor. GW 469.2
Let us rejoice that work which God can approve has been done in foreign fields. Let us lift our voices in praise and thanksgiving for the results of the work abroad. And still our General, who never makes a mistake, says to us, “Advance; enter new territory; lift the standard in every land. ‘Arise, shine; for thy light is come, and the glory of the Lord is risen upon thee.’ [Isaiah 60:1.]” GW 470.1
The time has come when through God's messengers the scroll is being unrolled to the world. The truth contained in the first, second, and third angels’ messages must go to every nation, kindred, tongue, and people; it must lighten the darkness of every continent, and extend to the islands of the sea. There must be no delay in this work. GW 470.2
Our watchword is to be, Onward, ever onward! Angels of heaven will go before us to prepare the way. Our burden for the regions beyond can never be laid down till the whole earth is lightened with the glory of the Lord. GW 470.3
