Why is trusting God's word important for Christians?

In the face of temptation, Jesus emphasized the importance of trusting in God's word by responding to the devil's challenges with Scripture. He quoted Deuteronomy 8:3, affirming that man does not live by bread alone but by the word of God. This principle reveals that our sustenance comes not from physical needs but from our relationship with God and reliance on His promises. Christians must anchor their faith in God's word to navigate life's trials effectively, recognizing that it provides guidance, comfort, and reassurance in times of temptation and testing.
