You know the commandments: "Do not commit adultery," "Do not murder," "Do not steal," "Do not bear false witness," "Do not defraud," "Honor your father and mother." Mark 10:19, NKJV.
People who will not admit the claims of God's law, which are so very plain, will generally take a lawless course; for they have so long taken sides with the great rebel in warring against the law of God, which is the foundation of His government in heaven and earth, that they are trained in this labor. In their warfare they will not open their eyes or consciences to light. They close their eyes, lest they shall become enlightened.
Their case is as hopeless as was that of the Jews who would not see the light which Christ brought to them. The wonderful evidences which He gave them of His Messiahship in the miracles that He performed, in healing the sick, raising the dead, and doing the works which no other had done or could do, instead of melting and subduing their hearts, and overcoming their wicked prejudices, inspired them with satanic hatred and fury such as Satan possessed when he was thrust out of heaven. The greater light and evidence they had, the greater was their hatred. They were determined to extinguish the light by putting Christ to death....
Our work should be to embrace every opportunity to present the truth in its purity and simplicity where there is any desire or interest to hear the reasons of our faith. Those who have dwelt mostly upon the prophecies and the theoretical points of our faith should without delay become Bible students upon practical subjects. They should take a deeper draft at the fountain of divine truth. They should carefully study the life of Christ and His lessons of practical godliness, given for the benefit of all and to be the rule of right living for all who should believe on His name. They should be imbued with the spirit of their great Exemplar and have a high sense of the sacred life of a follower of Christ.--Testimonies for the Church 3:213, 214.
