President George Q. Cannon:
“The Lord our God has sent us here to get experience in these things so that we may know the good from the evil and be able to close our hearts against the evil. . . . It is true that some have greater power of resistance than others, but everyone has the power to close his heart against doubt, against darkness, against unbelief, against depression, against anger, against hatred, against jealousy, against malice, against envy. God has given this power unto all of us, and we can gain still greater power by calling upon Him for that which we lack. If it were not so, how could we be condemned for giving way to wrong influences?
“There could be no condemnation for our doing what we could not help; but we can help yielding to wrong influences and being quarrelsome and selfish. We can help giving way to the spirit of theft, and we can resist the spirit of lust. God has given us power to resist these things, that our hearts may be kept free from them and also from doubt; and when Satan comes and assails us, it is our privilege to say, ‘Get thee behind me, Satan, for I have no lot nor portion in you, and you have no part in me. I am in the service of God, and I am going to serve Him, and you can do what you please. It is no use you presenting yourself with your blandishments to me. You come and try to insinuate into my heart evil thoughts about the servants of God or about the work of God, and I will not listen to you; I will close my heart against you. . . .’
“Whenever darkness fills our minds, we may know that we are not possessed of the Spirit of God, and we must get rid of it. When we are filled with the Spirit of God, we are filled with joy, with peace and with happiness no matter what our circumstances may be; for it is a spirit of cheerfulness and of happiness.” ( Gospel Truth, 1:19–20.)
