There are lessons for us to learn at this time from the experience of those who labored for God in past generations. How little we know of the conflicts and trials and labors of these men, as they fitted themselves to meet the armies of Satan. Putting on the whole armor of God, they were able to stand against the wiles of Satan.These men who in the past gave themselves to God and to the uplifting of His cause were as true as steel to principle. They were men who would not fail nor be discouraged; men who, like Daniel, were full of reverence and zeal for God, full of noble purposes and aspirations. They were as weak and helpless as any of those who are now engaged in the work, but they put their whole trust in God. They had wealth, but it consisted of mind and soul culture. This every one may have who will make God first and last and best in everything. Although destitute of wisdom, knowledge, virtue, and power, we may receive all these if we will learn from Christ the lessons that it is our privilege to learn. 
We need to make use of the youth who will cultivate honest industry, who are not afraid to put their powers to task. Such youth will find a position anywhere, because they falter not by the way; in mind and soul they bear the divine similitude. Their eye is single, and constantly they press onward, and upward, crying, Victory. But there is no call for the indolent, the fearful and unbelieving, who by their lack of faith and their unwillingness to deny self for Christ’s sake, keep the work from advancing. God calls for those who will be workers together with Him. Connected with Christ, human nature becomes pure and true. Christ supplies the efficiency, and man becomes a power for good. Truthfulness and integrity are attributes of God, and he who possesses these attributes possesses a power that is invincible.
