When the Lord was tempted in the wilderness, He used Scripture to counter the devil’s attempts to sway Him. The first passage Jesus quotes is from Deuteronomy, telling the devil and reminding us that our lives depend upon God and His Word alone. The more we hide God’s Word in our hearts, the less we will want to sin against Him and the more we will be empowered to resist when temptations come. Following Jesus truly changes everything for us.
Theologians classify God’s revelation of Himself into two categories. God’s general revelation is seen in the beauty of nature and points to Him, but not in a way that can tell us exactly how to be saved. The Bible is God’s special revelation, His unique and specific Word that tells us directly all we need to know to be reconciled to Him.
Since God is good, all He has taken care to communicate to us in His Word is also good and for our benefit. The road to personal ruin begins with the slightest detour away from whatever God has said. His words are peace and life.
