If those who hide and excuse their faults could see how Satan exults over them, how he taunts Christ and holy angels with their course, they would make haste to confess their sins and to put them away. Through defects in the character, Satan works to gain control of the whole mind, and he knows that if these defects are cherished, he will succeed. Therefore he is constantly seeking to deceive the followers of Christ with his fatal sophistry that it is impossible for them to overcome. But Jesus pleads in their behalf His wounded hands, His bruised body; and He declares to all who would follow Him, “My grace is sufficient for thee.” ... Let none, then, regard their defects as incurable. God will give faith and grace to overcome them.
We are now living in the great day of atonement. In the typical service, while the high priest was making the atonement for Israel, all were required to afflict their souls by repentance of sin and humiliation before the Lord, lest they be cut off from among the people. In like manner, all who would have their names retained in the book of life, should now, in the few remaining days of their probation, afflict their souls before God by sorrow for sin and true repentance. There must be deep, faithful searching of heart. The light, frivolous spirit indulged by so many professed Christians must be put away. There is earnest warfare before all who would subdue the evil tendencies that strive for the mastery.—The Great Controversy, 489. WGD 134
So everyone may be able, through his own experience, to “set his seal to this, that God is true.” John 3:33, A.R.V. He can bear witness to that which he himself has seen and heard and felt of the power of Christ. He can testify: “I needed help, and I found it in Jesus. Every want was supplied, the hunger of my soul was satisfied; the Bible is to me the revelation of Christ. I believe in Jesus because He is to me a divine Saviour. I believe the Bible because I have found it to be the voice of God to my soul.” MH 461
Now be ye not stiffnecked, as your fathers were, but yield yourselves unto the Lord, and enter into His sanctuary, which he hath sanctified for ever; and serve the Lord your God, that the fierceness of his wrath may turn away from you. 2 Chronicles 30:8, KJV
