Since Satan’s greatest weapon is getting humanity to doubt God’s Word, you and I must respond with faith, with that which heartens us, not hardens us, in His Word. The key passage of this message is:
Psalm 95:6-9: (6) O come, let us worship and bow down: let us kneel before the Lord our maker. (7) For he is our God; and we are the people of his pasture, and the sheep of his hand. To day if ye will hear his voice, (8) Harden not your heart, as in the provocation, and as in the day of temptation in the wilderness: (9) When your fathers tempted me, proved me, and saw my work.
