God has provided that we shall not be tempted above what we are able to bear, but that with every temptation He will make a way of escape. If we live wholly for God, we shall not allow the mind to indulge in selfish imaginings. CCh 166.4
If there is any way by which Satan can gain access to the mind, he will sow his tares and cause them to grow until they will yield an abundant harvest. In no case can Satan obtain dominion over the thoughts, words, and actions, unless we voluntarily open the door and invite him to enter. He will then come in and, by catching away the good seed sown in the heart, make of none effect the truth. CCh 166.5
It is not safe for us to linger to contemplate the advantages to be reaped through yielding to Satan's suggestions. Sin means dishonor and disaster to every soul that indulges in it; but it is blinding and deceiving in its nature, and it will entice us with flattering presentations. If we venture on Satan's ground, we have no assurance of protection from his power. So far as in us lies, we should close every avenue by which the tempter may find access to us. CCh 166.6
Every Christian must stand on guard continually, watching every avenue of the soul where Satan might find access. He must pray for divine help and at the same time resolutely resist every inclination to sin. By courage, by faith, by persevering toil, he can conquer. But let him remember that to gain the victory Christ must abide in him and he in Christ. CCh 166.7
Everything that can be done should be done to place ourselves and our children where we shall not see the iniquity that is practiced in the world. We should carefully guard the sight of our eyes and the hearing of our ears so that these awful things shall not enter our minds. CCh 166.8
Do not see how close you can walk upon the brink of a precipice and be safe. Avoid the first approach to danger. The soul's interests cannot be trifled with. Your capital is your character. Cherish it as you would a golden treasure. Moral purity, self-respect, a strong power of resistance, must be firmly and constantly cherished. There should not be one departure from reserve; one act of familiarity, one indiscretion, may jeopardize the soul in opening the door to temptation, and the power of resistance becomes weakened.237The Adventist Home, 410-404 CCh 167.1
