Satan is ever intruding himself between the human soul and God. He is ever seeking to make the human agent voice his suggestions rather than the words of God....
How little did Peter understand his own weakness. He could not discern but that his spirit was all right, even when he sought to make of none effect the solemn words of Christ that opened to them [the disciples] a future full of sorrow and of suffering, both to Him and to them. Christ saw that unless Peter was changed in spirit, he would not be able to endure the test and the trial of his Lord's rejection, humiliation, condemnation, and death. To his Master's warning words he responded, “Lord, I am ready to go with thee, both into prison, and to death. And he said, I tell thee, Peter, the cock shall not crow this day, before that thou shalt thrice deny that thou knowest me.”
We see how human nature can be deceived, how human nature can be misled, because Satan is allowed to step in between the human soul and Jesus. The word of Christ needs to be spoken with authority, “Get thee behind me, Satan.” Let Me come close to My servants, that they may not be overcome, that they may believe My words rather than the words of deceivers, for what I speak is truth and righteousness....
God's people, rescued from the fire by Jesus Christ, have a sense of their sin, and feel humbled and ashamed. God sees and recognizes their repentance and notes their sorrow for sin, which they cannot remove or cancel themselves; but as they pray, their prayers are heard, and this is the reason that Satan stands by to resist Christ.... He steps in between the repenting, believing soul and Christ. He seeks to cast his hellish shadow before that soul, to dampen faith, and to make of none effect the words of God....
If Satan stands between the soul and Jesus Christ, then the love and acceptance and pardon of Christ is eclipsed. Men and women will be constantly striving to prepare a robe of righteousness to cover their deformity and sin, whereas Christ wants them to come to Him just as they are, and believe in Him as their personal Saviour. In His tender love a forgiving Father brings forth His best robe in which to array His returning child.—Letter 65, 1894 (Manuscript Releases 7:201-203). CTr 275
The mother who permits her child to be nourished by another should consider well what the result may be. To a greater or less degree the nurse imparts her own temper and temperament to the nursing child. MH 383
And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat: but I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren. Luke 22:31-32, KJV
