If you ever have a bad day, you can always look to the cross.
Humans will most certainly let you down. If you are hoping a particular person won't fail you, your hope is misplaced. Human love is so conditional. It's a woeful state we're in. This sounds dismal, but it's okay when you look to the cross.
See, in the cross you always have a reminder that someone is so bent on having you that He died for you. And this was done not because you were at your finest, but because of a love with no strings attached. It is easy to forget this truth, but I can think of no greater reminder that you are loved than the cross.
