When the hearts of men are softened by the presence of the Spirit of God, they are more susceptible to impressions of the Holy Spirit, and resolves are made to deny self and to sacrifice for the cause of God. It is when divine light shines into the chambers of the mind with unusual clearness and power that the feelings of the natural man are overcome, that selfishness loses its power upon the heart, and that desires are awakened to imitate the Pattern, Jesus Christ, in practicing self-denial and benevolence. The disposition of the naturally selfish man then becomes kind and pitiful toward lost sinners, and he makes a solemn pledge to God, as did Abraham and Jacob. {YRP 90.1}
Heavenly angels are present on such occasions. The love of God and love for souls triumphs over selfishness and love of the world. Especially is this the case when the speaker, in the Spirit and power of God, presents the plan of redemption, laid by the Majesty of heaven in the sacrifice of the cross. . . .
God has given man a part to act in accomplishing the salvation of His fellow men. He can work in connection with Christ by doing acts of mercy and beneficence. But he cannot redeem them, not being able to satisfy the claims of insulted justice. This the Son of God alone can do, by laying aside His honor and glory, clothing His divinity with humanity, and coming to earth to humiliate Himself and shed His blood in behalf of the human race.
In commissioning His disciples to go "into all the world, and preach the gospel to every creature" (Mark 16:15), Christ assigned to men the work of spreading the gospel. But while some go forth to preach, He calls upon others to answer to His claims upon them for tithes and offerings with which to support the ministry and to spread the printed truth all over the land.--Testimonies, vol. 4, pp. 470-472.

Then was there such a revelation of the glory of Christ as had never before been witnessed by mortal man. Multitudes who had reviled His name and despised His power confessed themselves disciples of the Crucified. Through the co-operation of the divine Spirit the labors of the humble men whom Christ had chosen stirred the world. To every nation under heaven was the gospel carried in a single generation.
