The servants of Christ are to prepare no set speech to present when brought to trial for their faith. Their preparation is to be made day by day, in treasuring up in their hearts the precious truths of God's Word, in feeding upon the teaching of Christ, and through prayer strengthening their faith; then, when brought into trial, the Holy Spirit will bring to their remembrance the very truths that will reach the hearts of those who shall come to hear. TSS 106.2
God will flash the knowledge obtained by diligent searching of the Scriptures, into their memory at the very time when it is needed. But if they neglect to fill their minds with the gems of truth, if they do not acquaint themselves with the words of Christ, if they have never tasted the power of His grace in trial, then they can not expect that the Holy Spirit will bring His words to their remembrance. They are to serve God daily with their undivided affections, and then trust Him.—Sabbath-School Worker, October, 1896. TSS 106.3
