Psalms 41:11
By this I know that thou favourest me, because mine enemy doth not triumph over me
So many times, Christians will ask God why is he letting the enemy attack. They will tell God how they have served him and think that he should stop the attack. They never stop to think that they are under attack because they serve God. They also never stop to think that even though they are under attack, the enemy is still losing. God is protecting you from defeat. It may be a hard battle, but if you hold to God, you will win.
