Some question, "Why is God allowing this to happen to me?" or "What did I do to deserve this?" or "Where's God???"
I love this quote from Loves Comes Softly and think it sums it up best - "The truth of God's love is not that he allows bad things to happen. It's His promise that He'll be here with us when they do."
Nothing that ever happens in our lives catches God off guard or by surprise. He's authored the story of our lives from beginning to the end and promises that His plans are to give us hope and a future. He tells us in Matthew 6 that He even feeds the birds of the air. You and I are worth far more to Him than the birds. Your concerns are His concerns. He cares for you.
Instead of allowing the devil to use these situations to defeat you, allow them to drive you closer to God. He promises that when we draw near to Him, He will draw near to us. In every situation we face, may it "lead us to the Rock" which is Christ Jesus.
From the end of the earth I call to you when my heart is faint. Lead me to the rock that is higher than I. Psalm 61:2
