“You will keep in perfect and constant peace the one whose mind is steadfast [that is, committed and focused on You—in both inclination and character], Because he trusts and takes refuge in You [with hope and confident expectation]. Trust [confidently] in the Lord forever [He is your fortress, your shield, your banner], For the Lord God is an everlasting Rock [the Rock of Ages]." -Isaiah 26:3-4

Sometimes hard times happen. They come when we least expect it, under the fold of joyful times. Times when everything seems just perfect, the enemy jumps at the opportunity to steal and destroy (that's kind of his thing).

He takes joy in taking moments of joy and attempting to turn them to ruin. And so we struggle.
