There is not an impulse of our nature, not a faculty of the mind or an inclination of the heart, but needs to be, moment by moment, under the control of the Spirit of God. There is not a blessing which God bestows upon man, nor a trial which he permits to befall him, but Satan both can and will seize upon it to tempt, to harass, and destroy the soul, if we give him the least advantage. Therefore however great one’s spiritual light, however much he may enjoy of the divine favor and blessing, he should ever walk humbly before the Lord, pleading in faith that God will direct every thought and control every impulse.
(MYP 62.1)
All who profess godliness are under the most sacred obligation to guard the spirit, and to exercise self-control under the greatest provocation. The burdens placed upon Moses were very great; few men will ever be so severely tried as he was; yet this was not allowed to excuse his sin. God has made ample provision for His people; and if they rely upon His strength, they will never become the sport of circumstances. The strongest temptation cannot excuse sin. However great the pressure brought to bear upon the soul, transgression is our own act. It is not in the power of earth or hell to compel any one to do evil. Satan attacks us at our weak points, but we need not be overcome. However severe or unexpected the assault, God has provided help for us, and in His strength we may conquer.—Patriarchs and Prophets, 421.
