If God be for us, who can be against us? Romans 8:31
Imagine yourself as actually looking at all your difficulties like an army lined up against you. Then realize you have a backing that can overcome them all. As you face these enemies of yours—discouragement, frustration, disappointment, hostility, weakness—ask yourself, “What shall I say to these things?” And the answer is, If God be for us, who can be against us?” Now, spend a minute realizing that God is for you and say this affirmation: “God is with me. God is for me. God is greater than all these things.” Then visualize these enemies of your peace and happiness as retreating, giving way before God’s power. Personalize the text by saying: “If God be for me, who can be against me?” The repetitive use of this text will give you an enormous sense of God’s presence and a powerful feeling of victory.
