Satan the devil has a plan to destroy us, and often he uses the four Ds listed below. For our spiritual safety, we must not be "ignorant of his devices" (2 Corinthians 2:11).
Disappointment. Any time we look to people we can be disappointed, but if we trust and believe in God, we won't be put to shame (1 Peter 2:6).
Discouragement. When we dwell on disappointments, it automatically leads to discouragement. But God has given us the Scriptures to encourage us (Joshua 1:5-8; John 14:1-3, 27).
Doubt. Discouragement left unchecked leads to doubt. When Peter took his eyes off Christ and focused on the waves, he doubted and could no longer walk on the water (Matthew 14:29-31).
Division. Doubts and worries can lead to division of our loyalties. These can also lead to divisions between people and distancing from God.
Being aware of these devices can help us fight against them and focus on God's plan instead. "Let us hold fast the confession of our hope without wavering, for He who promised is faithful" (Hebrews 10:23).
